Dolby Digital 5.1.. Or The Lack Thereof

So im wondering why with all the fanfare from BT, why the lack of 5.1 surround sound?!
Great HD PQ (On Sky, can't comment for other providers) yet bog-standard 2.0 stereo... WHY?

P13,
Is there any media provider in the UK that supports an app with 5.1 surround sound? Sky Go does not nor does bbc iplayer, netflix or blinkbox
sky twitter account a customer ask why sky go streams are worst then sd and yet bt and eurosports apps stream in hd. Reply from mod, oh thats easy the files for hd are some huge that sky go can't play them and no app can stream hd due to this and so when they say they are they're really sd streams, if there was any way around this we would have done it now.

It is producing the Dolby Digital file but not the encoded .m2v file?

I am trying to encode as MPEG-2. I slightly modified DVDBest Quality 90 minutes and dragged my QT file and these settings to the batch window. I submitted a few clips successfully, however the last clip does not seem to want to generate a video clip, it just produces the Dolby Digital Professional 2.0 file. I tried this a few times with the same result.
Any ideas what might be wrong?

Depending on what version of OSX you're running, and how the data was transferred, you may be out of luck.
If you're running Lion, and your backups were made to a directly-connected external HD (ie, not a Time Capsule or other network location), you may be able to get Time Machine to "associate" the new disk with the old backups. See #B6 in Time Machine - Troubleshooting, especially the pink box there.
If you're running Snow Leopard, you might be able to do a full system restore of your backups to the new HD. See Time Machine - Frequently Asked Question #14 for detailed instructions. That should leave a "trail" that Time Machine can follow to "associate" the new drive with the old backups. Unfortunately, that doesn't always work, and there's no way to do it manually, as there is with Lion.

ADDT DOCUMENTATION - Or the lack thereof !

Have just installed DWCS3 + ADDT. Wanted to read up on Nextensio only to find that there is no doco on this. Here is what I did:
Opened up the Create Dynamic Lists (used to be called Nextensio Lists) wizard and clicked on the Help button. This takes me to an Adobe website and provides the informative message of:
Not Found
The requested URL /en_US/Dreamweaver/9.0_ADDT/MXK3_045310_NeXTensio_List_Wz.htm was not found on this server.
So I am wondering if the current distribution of ADDT is "pre release" since there is no Help button on the toolbar anymore.
Some advice from Adobe on this would be nice as the Help available is pretty sparse compared to the Help available for Kollection Pro. Quite dissapointing in fact. As a result, I have to keep closing down DW CS3/ADDT and open up DW 8 / Kollection Pro. All because of a minor bug in Kollection Pro which I came across 3 days ago. That bug forced me to insall DW CS3 and ADDT and waste time on what was a tight project. Not happy Adobe !

Hi Gunther
Thanks for the reply and your hint on finding the help. Yes I eventually found it but my main gripe back then in May was that it was incomplete when I clicked on the help button in one of the ADDT Server behaviour wizards ( I was taken to a Page Not Found error ) and was not available from the DW Help dropdown list under the main menu Help button.
Yes, I could understand what you were getting at and I will be applying your Spry/PHP article in my next project - just wish I had come across it a bit earlier as I could have used it in the current project which includes hundreds of images from a number of different categories. Thanks again.
I understand that there are differences between the old Kollection and ADDT however, the fact that no attempt was made, nor has there been made as yet, to prepare or update the old tutorials for ADDT. This is a significant failure as the How To's were a godsend to me and I will bet London to a Brick, many more who purchased the old Interakt products. They must have saved me hours upon hours and also gave me an insight into using the advanced features of the product which allowed me to take full advantage of what the product offers. What this failure by Adobe means is that people who are coming to the ADDT for the first time and have not had the benefit of the tutorials included in previous versions will face an uphill battle coming to terms with what they have purchased which in turn may de-value ADDT. This failure I believe is also repeated in DW CS3 as appears not to include the tutorial material included in previous versions. For example, where are the Tutorials for CS3 ?? They are no longer included in the Getting Started section of Help as was the case with previous versions and the novice is instead referred to the lightweight trivial examples in the video workshop. So, if you and I have any influence over Adobe then perhaps they will take some notice of my rant and pick up their act. Lets face it, they are making heaps and can surely afford to invest in quality tutorials for their product especially one such as ADDT.
Best regards,

Request for THE dolby digital answer from Apple

My old set up was component video and optical into AV reciever. All worked well, HD movies had DD 5.1 soundtrack.
Now my new HDMI set up doesn't seem to send 5.1 across.
1. I have dolby digital set to on
2. I played a known DD HD film 'In Bruges' but no matter what could not pick up DD 5.1 via HDMI, my AV reciever Sony 2400ES (brand new model) just piccks up stereo
3. The soundtrack worked beautifully when sent via optical in full DD 5.1
4. I tried to select the 5.1 audio track via play/pause button which seemed like a great solution just in case both stereo and DD 5.1 were being sent via hdmi and confusing amp, but no selection option exists.
what worries me is the lack of response (that I can find) from apple on what as usual seems to be a huge amount of postings on this subject.
What would be handy Apple are:
1. A FREE dolby digital 5.1 movie/tv episode to 'play with' on with a selectable soundtrack option to allow you to check every option on your home cinema set-up without wasting £4-£5 every 48hrs. And I know the start up movie is said to be 5.1 but it lasts for a few seconds!!
2. A definitive answer on this issue
3. A difinitive LIST of movies and their soundtrack options, why does it take the pre buying screen to confirm/deny that the HD movie is indeed in 5.1, can't you use the same nomenclature as years and years worth of DVD covers, PUT Dolby Digital 5.1 and the little 6 speaker logo not just the double D's, which in DVD land usually just denote dolby stereo.
4. some administrator postings, I can't remember (apologies if wrong) seeing OFFICIAL responses in these forums, just loads of confused owners. And I remember a couple of years ago when my 80GB firmware update rendered my ipod dead, and it took WEEKS to find out how to fix it, which was a roll back until the new firmware was released.
I love 720p movies in 5.1 DD via HDMI, or rather I love the idea of them. It seems daft that to get it all as it should be I need to revert to component and optical

In Bruges - in 5.1 works fine on my ATV with it connected to my AV receiver via HDMI

It seems that your HDMI input on your receiver has not been configured to accept 5.1. You may need to check the settings of the receiver.
{quote}I tried to select the 5.1 audio track via play/pause button which seemed like a great solution just in case both stereo and DD 5.1 were being sent via hdmi and confusing amp, but no selection option exists.{quote}
This option only exists in 2.3 if you have extra audio tracks (e.g Director's Commentary, Alternate Language). If you have the "default" 2 tracks of AAC Stereo and AC3 then the Audio tab does not appear.

However, no matter if it is a few seconds or not it still plays in 5.1. Again, my ATV to my receiver via HDMI flips over to 5.1 when playing the startup movie, back to Stereo when negotiating the menus then back to 5.1 when i play a movie

I have plenty of DVD's where the Double D logo is shown and then right after it the words: Dolby Digital. Anyway, head on over to www.appletvjunkie.com if you want a list.

Again, no issues here with 5.1 over HDMI. You say you have a brand new receiver - perhaps the settings are not quite right on it to accept 5.1 over HDMI. Just a thought.
I can't see how a "known' film that plays in 5.1 over Optical but does not over HDMI be a problem for Apple. It's not like they can add "Do not send over HDMI" flags.
Yes, there is a big thread on AC3 not working with the 2.3 update, but that is down to the lack of AAC track on peoples own converted movies, and nothing to do with it being sent over Optical or HDMI. I don't believe Apple would be missing the AAC track on a movie they rent.
Cheers

Does the digital optical input recognise Dolby Digital?

Hey guys,
I was wondering if you could help clarify something for me. I have an Astro Gaming A30 Audio System that I use when playing my PS3. It's a gaming headset with pinpoint-accurate 7.1 Dolby and Dolby Headphone surround sound. Here's a link to the web page if you want to know more about it - http://www.astrogaming.com/products/detail/80/A30-Audio-System/.
Now, at the moment I have the PS3 connected directly to the A30 Audio System with a digital optical cable. In the PS3 settings, I have it set to output Dolby Digital 5.1 as this is the format that the A30 Audio System uses. This setting is important because it's what gives me the surround sound in my headphones. Ok, we're almost at my question...
Recently, I've been thinking of buying a capture card so I can record my game plays and upload them to YouTube. The capture card that I'm thinking of getting is the Blackmagic Design Intensity Pro. Here's a link to the web page - http://www.blackmagic-design.com/products/intensity/.
My question is - since there is no output on the A30 Audio System, and therefore no way to route the sound into my Mac from it, I need to first send the sound from the PS3 into the Mac (for recording) and then re-send the sound from the Mac into the Astro A30s (for listening). If I do this, will I lose the Dolby Digital format that was originally output from the PS3? I don't mind recording the audio in stereo, but it's essential that the Dolby Digital sound goes to the Astro A30s. Otherwise I won't have proper surround sound. And if you went to the website, you would have noticed that they're pretty expensive. So playing in surround sound is very important to me, as I paid top dollar for them.
Anyway, if you can clarify that for me it would be much appreciated. Thanks for your time.
Regards,
Daniel

Sure there's a difference it depends completely on the original sample rate of the audio recorded otherwise the best built in audio can do is 48/24, so trying to go out at 96 will force resampling[without a capable app running]. But in terms of resampling, if you use the card then you should be able to use 96/32.
Have you properly adjusted AMS settings; so that the card is in Properties at 96? Still the only governing factor there is whatever software governs the PCI card. I don't get the problem you're having here, what is the connection to the machine, optical?

ITunes rented movie not outputting Dolby Digital 5.1 audio

The problem with the downloaded movie (Real Steel HD) is
that the Dolby Digital 5.1 (English) audio is not being putput. The movie is only playing back in
"stereo" mode. When playing back on iTunes there are four audio tracks
to choose from:
1. English 1 (This plays stereo)
2. English 2 (NO SOUND) - I believe this should be the Dolby Digital track
3. French (This plays stereo)
4. Spanish (This plays stereo)
Neither of the two English tracks is outputting Dolby Digital 5.1 audio.
I have confirmed that my PC is capable of up to 7.1 surround sound and
my A/V receiver is capable of even more. I have updated both the ATI
Radeon 4500 driver and the Realtek drivers. I have tested and
confirmed that my PC is capable of outputting sound to all 5 of my
speakers and my subwoofer, HOWEVER when playing back the rented movie
in iTunes the maximum audio is stereo. I have the latest version of
iTunes installed, so that shouldn't be the problem.
I have also purchased another movie advertised as Dolby Digital 5.1
audio (The Bourne Supremecy HD) but I am afraid to begin my 24-hour
viewing period because of these audio problems being unresolved.
My question is: Are there known issues of movies purchased on iTunes
and played back on a Windows 7 PC not playing the Dolby Digital
tracks? If so, is there a fix for this via an iTunes settings change
or a Windows update patch?
From the four audio tracks that I listed above, I believe track 2 is
the Dolby Digital track, yet there is NO SOUND when that track is
selected.
Please help, as this is pretty frustrating when your movie night is ruined for the family especially after you've paid for and waited for the movie to download.

I managed to get my DD tracks working.
First had to update itunes to the latest version (10.7.0.21) to get rid of the out of sync sound problem
Then updated the realtek driver. There was an update directly in the realtek website (mine is the HD Audio): http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=14&PFid=24& Level=4&Conn=3&DownTypeID=3&GetDown=false
After all that. I tunes wasn't allowing anymore to select the Doubly Digital 5.1 tracks (an improvement).
Then went to the windows properties for the realtek optical output and checked both options to allow application exclusive access and to have priority (http://dailykermit.wordpress.com/2009/09/11/windows-7-exclusive-device-control/)
After all this, I was able to enjoy my rental

Dolby digital via Toslink

Hardware
Mac mini (mid 2011)
Yamaha YAS-101
I've connected a mini to a Yamaha YAS-101 via Toslink hoping to receive Dolby Digital 5.1. The problem is that the YAS-101 detects the signal as stereo. I was under the impression that it shouldn't be a problem to achieve this via Toslink? Tested with Itunes and VLC.
The YAS-101 detects DD when playing a bluray from a PS3 so shouldn't be a problem there.
Thankful for any help.

If your Mac Mini has a HDMI port, it's one of the few Apple products that does audio (5.1) and video through the HDMI port.

IPhone Dolby Digital Pass-through

I can see from the Tech Specs of both the iPad 2 and 3 that they have the ability of Dolby Digital Pass-through using the Apple Digital AV Adaptor.
Can anyone confirm if the iPhone 4 or 4S also have this ability?
It's not specifically mentioned on their Tech Specs pages, but the hardware capabilities are almost identical.
Cheers.

Netflix Dolby Digital 5.1 gone after udpate

Hi,
Is anybody (or everybody) else having that problem ?
Last week I was playing Netflix movies in Dolby Digital 5.1 but now the same movies on the same hardware (Apple TV/ AV reciver) are not Dolby Digital anymore but only prologic.
Other Apple TV items (ie. movies, shows, itunes festival) have no problems streaming in 5.1.
It look like this happen at the time of the latest Apple TV OS update.
Is this a Netflix issue or a Apple issue ?
Tried to contact Netflix....they don't have a clue.
PS, I have the latest generation of Apple TV and I update my Apple TV OS last week (so i'm up to date).

I've encountered the exact same issue. Ever since the latest Apple firmware update I can't get the Netflix app to send a Dolby Digital signal to my receiver. I've tried everything but it just does Pro Logic II. This is for content on Netflix that I know is Dolby Digital 5.1 supported.
As you've said, Dolby Digital still works fine for other content (iTunes festival, movies, etc) but Netflix doesn't seem to trigger it. Something is not quite right with this firmware and Dolby Digital. I can't remember for sure now but I think that, before this firmware, my receiver always had the Dolby Digital light on when the Apple TV was on (even when on the home screen). It now seems to be Pro Logic II all the time except for specific content.

Digital Connections, SPDIF and Dolby Digital Info

I have noticed that many people have problems using their digital connections, so I put together this info to try and explain the difference between digital and analogue, and how to use them.
Digital ConnectionsDigital connections come in two standard forms, optical and coax. They both give you exactly the same result, the only difference is the medium (material) through which the signal travels. The thing to remember about digital is that for ordinary, uncompressed sound, it will only carry a stereo signal. So, if you like to use CMSS with your music, or you try the speaker test function, optical/coax is useless as you only hear the front left/right speakers.
Movies wth Dolby Digital (AC3) & DTSMovies on DVD often use encoded audio in the form of Dolby Digital (AC3) or DTS. This means that all 6 channels are compressed into a single stream of digital data. A decoder is required to extract the channels and send the sound to the correct speakers. There are three ways to do this.
) Pass the AC3/DTS signal to a external decoder. This is where your optical/coax connection is used. To go down this route, you must first have a set of speakers or a decoder that supports Dolby Digital. In your DVD software, select 'SPDIF' as the audio output method and 'SPDIF Pass-through' in your soundcard options. What this does is tells both the software and soundcard to leave the audio from the DVD in compressed form and send it straight through the digital outputs. Your digital speakers/receiver will do all the decoding to give you full surround sound. Please note that this is the only way to get 6 channels through an optical/coax cable.
2) Decode the AC3/DTS with your Sound Blaster.You should choose this option if you don't have an external decoder. In the DVD software, select 'SPDIF' as the audio output method and make sure that 'SPDIF Pass-through' in the souncard options is off. The DVD software will now pass the compressed audio to your soundcard, which will then decode the data. The soundcard will output the 6 channels using the analogue connections (or digital DIN, more on this later). If you try to use a digital optical/coax connection to your speakers, you will only hear faint sounds from the front left/right speakers.
3) Decode the AC3/DTS with software.If you have a soundcard that doesn't support Dolby Digital (like the SB Li've! 24-bit) and you don't have digital speakers, the only way for you to get surround sound in movies is to use software to decode the AC3/DTS. The free versions of DVD software you get with hardware often don't support this feature, you will most likely need a full version. First select 'Dolby Digital' or 'DTS' decoding in the DVD software audio options (you must select the right sound format for the movie you are watching). Then make sure that 'SPDIF Pass-through' in the soundcard options is off. As with method (2) you must connect your speakers with the 3 analogue cables, not optical/coax.
PC GamesPC games usually use technologies like as EAX to create surround sound, not Dolby Digital. So even if your speaker system has a Dolby Digital decoder, it will be of no use when playing games. The EAX processing is done on the soundcard, and the 6-channel sound is output via the analogue (or digital DIN if available). So you still need analogue connections to your digital speakers for games, if you just use an optical/coax cable you will only get the front left/right sound.(N.B. X-Box games do support Dolby Digital, so if you connect your X-Box to your Dolby Digital receiver/speakers with the optical cable, you can get full surround sound.)
Creative's 4-pole mini-jack & Digital DINYou can only get the full use out of this connection when used between Creative Sound Blasters and compatible Creative speaker systems. It is the digital equivalent of the analogue connections, but instead of using 3 stereo sockets, you use just one digital socket. There are 4 conducting connections in the socket (unlike coax which has two) so there are enough connections to carry 3 different digital stereo signals (front R/L, rear R/L and Sub/Centre). You will probably require a 4-pole mini-jack > DIN converter to connect your Creative speakers to this socket. Using this connection will allow you to get surround from games (unlike SPDIF). However the digital DIN input on some Creative speakers can't receive AC3/DTS data, so you may still require an optical/coax connection.
N.B. This digital socket on the Sound Blaster cards doubles as the digital coax output. If you don't have digital DIN, you can use a mono or stereo mini-jack > RCA converter to connect to the coax input on your speakers, as the front R/L or AC3/DTS signals are sent through the tip of the plug.

Der Digitale Anschluß
Ich habe beobachtet, daß viele Leute Fragen zu den Sound-Anschlüssen haben, daher trage ich hier einige Infos zusammen und erkläre die Unterschiede in der Verwendung der digitalen und analogen Anschlüsse.
Digitale Anschlüsse – S-PDIF & Toslink
Am PC gibt es zwei häufig verwendete digitale Anschlußformate optisch (Toslink) und koaxial (S-PDIF).
Im Prinzip erzielen beide Anschlüsse genau das gleiche Audio-Ergebnis.
Der primäre Unterschied ist das Medium ( das Material ) durch das das Signal übertragen wird. ( Glasfaser oder Kupfer )
!! Update !!
Ein wichtiger Aspekt in der Auswahl von digital-optischen Anschlüssen erklärt sich durch das Vermeiden einer sogenannten „Brummschleife“, d.h. eine elektrisch leitende Verbindung zweier Geräte muß vermieden werden.
( mit Lichtwellenleiter - LWL- z.B. mit dem Anschluß-System Toslink )
In der Elektrotechnik ( Niedervolttechnik ) wird oft der „Negative“ Pol der Spannungsversorgung über das elektrisch leitende Gehäuse ( die sogenannte Masse )geführt. Das spart einerseits einen weiteren Kabelweg ( also Kupfer ) ein und ergibt eine mehr oder weniger wirksame (Ab-) Schirmung. Diese Schirmung soll die elektronische Schaltung vor elektromagnetischen, hochfrequenten und niederfrequenten Störeinflüssen je nach Ausführung der Schirmung schützen.
Üblicherweise besitzt jedes elektronische Gerät eine eigene Spannungsversorgung. Netzteile in elektronischen Geräten unterscheiden sich in der Art der Spannungsumformung, in der Höhe der Spannung, in der zur Verfügung gestellten Leistung, durch verschiedene Bauarten und unterschiedliche Bauteil-Tolleranzen entstehen somit verschiedenste Masse-Potentiale.
Werden solche Geräte durch elektrisch leitende Kabel verbunden, kommt es zu einem Ausgleich der verschiedenen Masse-Potentiale. Ein negatives Ergebnis der Verbindung von TV-Geräten oder PC-Komponenten mit Audio-Komponenten ist oft eine hörbare Beeinträchtigung von Audio-Signalen - ein tieffrequentes Brummen.( auch Brummschleife oder Masseschleife genannt )
Hierfür verantwortlich zu machen ist eine elektrisch leitende Verbindung. In der HiFi-Technik ist das in der Regel ein Koaxialkabel und dessen Schirmung.
Vermeidung u. Reduzierung dieser Störgeräusche Ansätze
!! Der einfache Weg !!
Einsatz einer optischen Signal- / Datenübertragung mit Lichtwellenleiter
- Glasfaser als Trägermaterial
( Einsatz einer Datenübertragung ohne elektrisch leitende Verbindungen )
aufwendige Wege
Einsatz einer Galvanischen Trennung - mit einem Ground-Isolator
(Massetrennung )
+ die elektrische Verbindung der Schirmung wird umgangen
- aber Leistungs- & und Klangverlust(geringere Dynamik)
- Verwendung von ( hochwertigen ) symmetrischen Verbindungen
( „PLUS“ „MINUS“ „Masse“)
+ Trennung der Schirmung an einer „Seite“ des Kabels möglich
[bei Koaxialkabel unsinnig weil eine Ader zerstört wird und
anschließend dieses Kabel wertlos ist ]
- sehr große Anschlüsse
- Profibereich
- Einsatz einer zentralen Spannungsversorgung für alle miteinander
verbundenen Geräte
Nachtrag
Bitte nicht verwechseln mit Netzbrummen - die Einstreuung der Netzfrequenz 50 Hz ( EU ) oder 60 Hz ( US ) in den Audio-Signalweg das ist üblicherweise auf eine nicht ausreichende Entstörung oder(Ab-)Schirmung zurückzuführen ist.
- End - !! Update !!
Einige Vorbetrachtungen
Die traditionelle Ton-Übertragung ist ein unkomprimiertes Signal, es wird in Stereo übertragen.
Wenn du CMSS ( Creative Multi Speaker Surround simulierten Surround Sound ) aus deiner Stereo-Musik erzeugen willst oder der Sprach-Test abgerufen wird ( nur über den Center ) ist der digitale Anschluß ( optisch & koaxial ) unbrauchbar, denn es würden nur die Lautsprecher Front-Rechts und Front-Links angesprochen !! Es wird ein anderer Anschluß benötigt, der die Kanäle einzeln ansteuert.
Für das Format 5.1 ist das die Verbindung über die drei 3,5 mm Klinken-Stecker ( 3 mal 2 Kanäle ) mit der folgenden
Kanalzuweisung 5.1
Front R / Front L + Rear R + Rear L + Subwoofer / Center
Mehrkanalton in Filmen - DolbyDigital (AC3 / DD) oder DTS
Filme auf DVD verwenden häufig ein kodiertes Mehrkanal-Audiosignal, in der Form DolbyDigital ( AC3 / DD ) oder DTS. Bei dem gebräuchlichsten Format 5.1 werden 6 Signale ( 3 mal 2 Kanäle ) in einem digitalen Datenstrom zusammengefaßt und komprimiert = das Kodieren.
Nach der Übertragung des Signals muß aus diesem Datenstrom ein Decoder die entsprechenden Töne trennen und jedem Kanal zuordnen = das Dekodieren.
Drei Varianten der Decodierung sind möglich.
(1) - AC3 / DTS Signal wird zu einem externen Decoder geführt
Genau hier wird der optische / koaxiale Anschluß genutzt. Um diese Variante nutzen zu können, mußt du ein digitales Lautsprecher-Set oder einen Digital-Decoder ( z.B: Digital-Receiver ) besitzen, der die Dekodierung des gewünschten Formats ( DD, AC3, DTS) übernimmt. Für jedes Digital-Format benötigt man einen entsprechenden Decoder – das Handbuch weiß hier oft mehr – welches Format von welchem Gerät dekodiert werden kann !!
Wähle in deiner DVD-Software den zur digitalen Datenübertragung gewünschten Anschluß "S-PDIF"( Koaxial ) oder "Optisch" als Audio-Ausgang.
In den Soundkarten-Einstellungen muß die Option "S-PDIF-Durchschleifen" ( "SPDIF Pass-through" ) eingestellt werden.
Dadurch wird das Audio-Signal von der DVD in digitaler ( komprimierter ) Form direkt an die Digital-Ausgänge der Soundkarte weitergeleitet. Anschließend kann ein angeschlossener externer Decoder z.B. im digitalen Lautsprecher-System oder im Digital-Receiver die Decodierung übernehmen und es entsteht ein „Räumliches Klangbild“.
Bitte merken:
Daß ist der einzige Weg 5.1 Signale ( digital ) über ein koaxiales bzw. optisches Kabel zu übertragen.
(2) - AC3 / DTS mit der Soundkarte decodieren
Diese Variante ist zu verwenden, wenn du keinen externen Decoder / Receiver verwenden willst.
In der DVD-Software wird "S-PDIF" als Audio-Ausgang gewählt und es muß zwingend in den Optionen der Soundkarte "S-PDIF-Durchschleifen" ( "SPDIF Pass-through" ) deaktiviert werden.
Die DVD-Software wird jetzt das ( digitale ) komprimierte Audio-Signal an deine Soundkarte senden und dann werden dort die digitalen Daten decodiert. Die Soundkarte gibt dann die 6 Audio-Kanäle ( bei 5.1 ) über ihre drei analogen Anschlüsse aus ( 3 mal 3,5 mm Klinke ) mit folgender
Kanalzuweisung 5.1
Front R / Front L + Rear R + Rear L + Subwoofer / Center
Es wird in diesem Beispiel also ein 5.1-Lautsprecher-System benötigt, mit der analogen Anschluß-Option von drei Klinken-Steckern.
( also 3 x 2 Kanäle = 3 mal 3,5 mm Klinke )
- die Einspeisung eines digitalen Signals über DigitalDIN, ist mit dem optionalen digitalen E/A-Modulbei möglich ***
- wird hier ein optisches / koaxiales Kabel verwendest, hörst du nur schwache Töne der Front-Lautsprecher R + L
*** Bei Karten der SB073X-Serie verfügt diese Buchse nicht über die Digital-In-Funktion !! zur Unterstützung des digitalen E/A-Moduls )
[ mehr unten ]
(3) - AC3 / DTS mit einer Software decodieren
Wenn deine Soundkarte kein DolbyDigital unterstützt
( wie die SB Live! 24-bit ) und auch kein digitales Lautsprecher-System vorhanden ist, kannst du Raumklang
(Surrsound-Sound ) aus DV-Filmen auch über eine AC3 / DTS fähige Software erzeugen.
Gratis-DVD-Software-Versionen unterstützen diese Funktion häufig nicht, du benötigst dann eine Software-Voll-Version.
Wähle die gewünschte digitale Audio-Tonspur „DolbyDigital“ oder „DTS“, im Audio-Menü einer DVD.
Dann stelle sicher, das in den Soundkarten-Optionen "S-PDIF-Durchschleifen"
( "SPDIF Pass-through" ) ausgeschaltet ist.
Wie unter (2) mußt du deine Lautsprecher mit den drei analogen Kabeln anschließen und nicht optisch oder koaxial !! ( 3 mal 3,5 Klinke )
Kanalzuweisung 5.1
Front R / Front L + Rear R + Rear L + Subwoofer / Center
Generell sind bei zuvor genannten Varianten (1) – (3) auch andere mehrkanalige
Wiedergabeformate möglich.
In Abhängigkeit von der Ausstattung der Quelle also von der DVD. der CD. der TV-Karte, dem Game usw. sind andere Formate z.B. 2.0 / 2.1 / 4.0 / 4.1 / 5.1 / 7.1-Kanal Wiedergabe möglich.
PC Spiele
PC Spiele nutzen normalerweise Technologien wie EAX, die ihren eigenen Surround-Sound, ohne Verwendung von DolbyDigital erzeugen. Selbst wenn dein Lautsprecher-System einen DolbyDigital-Decoder besitzt, ist dieser für Games unbrauchbar. Denn die EAX Verarbeitung findet direkt auf der Soundkarte statt und die Ausgabe der 6 Kanäle ( 5.1 ) erfolgt über die analogen Ausgänge
( 3 mal 3,5 mm Klinke ) ( oder über DigitalDIN, wenn vorhanden *** ).
*** Bei Karten der SB073X-Serie verfügt diese Buchse nicht über die Digital-In-Funktion !! zur Unterstützung des digitalen E/A-Moduls ) [ mehr unten ]
Kanalzuweisung 5.1
Front R / Front L + Rear R + Rear L + Subwoofer / Center
Für Mehrkanalwiedergabe in Spielen benötigst du also Lautsprecher-Systeme mit analogen Anschlüssen oder einen Digital-Receiver mit analogem ( 5.1 ) Eingang.
Wenn du ein optisches / koaxiales Kabel verwendest, dann kannst du nur die vorderen Kanäle ( links / rechts ) hören.
!!! Notiz !!!
X-Box Spiele unterstützen DolbyDigital, wenn du deine X-Box mit einem DolbyDigital-Receiver oder einem digitalen Lautsprecher-System über optische Kabel verbindest, kannst du den vollen Surround Sound nutzen.
Die Sound Blaster Karten der SB073X-Serie bieten neben dem digitalen ( koaxial / extern ) Anschluß über den Anschluss Flexi-Jack auch noch einen weiteren Anschluß, direkt auf der Karte ( koaxial / intern )
Flexi-Jack - DigitalDIN
Wenn du kein digitales E/A-Modul ( Digital I/O-Modul ) benutzen kannst, ist es möglich mit einem Klinke-Chinch Adapter ( RCA-Adapter ), ein digitales Lautsprecher-System oder einen Digital-Receiver digital ( koaxial ) über den Flexi-Jack-Ausgang der Soundkarte zu verbinden. Alle MiniDin bzw. 3,5 mm Klinken-Stecker können in der Mono- oder auch in der Stereo-Ausführung verwendet werden, denn der mittlere / vordere Pin des 3,5 mm Klinken-Steckers überträgt das AC3 / DTS Signal. Dazu benötigt man eine der folgenden Verbindungen
3,5 mm Klinke ( Mini DIN ) auf Chinch - Adapter ( RCA-Adapter )
für den S-PDIF-Anschluß( koaxial ) an Lautsprecher-Systeme mit digitalem Eingang bzw. Digital-Receiver kann man folgende Varianten verwenden

2 issues with X-Fi Titanium software (Dolby Digital related)

These arnt anything major but worth fixing IMO.
1. There is a slightly noticable sound quality drop in nati've Dolby Digital sources when using the "Speakers" as the defualt device compared to using SPDIF in Windows playback devices.
For example I have a movie encoded in Dolby Digital, I use the optical input on my 5. and leave "Speakers" as default device in Windows playerback devices, this way I can add effects such as CMSS3D EQ etc, but leaving EVERYTHING off the SQ is not as good as selecting SPDIF in Playback devices, the major downside though is having SPDIF in windows audio panel bypasses any settings in the creative console.
I realise this may be an issue with Windows rather than Creative.
2. Dolby Digital remains enabled when Headphones is automatically Activated / When Dolby Digital is activated with headphones 5. sound is used but the center, sub and 2 rear channels dont get passed.
I have my entertainment mode set to 5. wich automatically switches to Headphones when I plug them in.
I used Windows playback devices to do a speaker check, this is always set to 5. and the creative console never overrides this.
When I test my headphones with DD off I hear all 6 channels in my headphones, when I enable Dolby Digital I only hear the front left and front right channel, if headphones mode is suppose to be automated it should automatically adjust for Dolby Digital either by disabling it until the headphones are unplugged or to pass all 6 channels to the headphones like it otherwise normally would.

Edit: I now installed the Dolby Digital Live drivers, that were hidden on the download page until I pressed "All".
The DDL option now appears under "Encoder", but still there's not sound coming through.

Dolby Digital Encoder Does Not Support Any Encoding Options

Is it just me, or are there no encoding options for the Dolby Digital encoder other than the bitrate?
How are you supposed to select the dialog normalization, dynamic range compression profile, etc. for your audio? Without these parameters set correctly, the audio will not be encoded correctly.

@jbowden:
> Adobe licenses the AC3 encoder that Encore uses from Dolby Laboratories. This is stated quite clearly in the splash screen, the box, and other materials distributed with Encore.
I didn't say otherwise. But what they license is the code, not the implementation. Implementations are supposed to be submitted to Dolby for approval, and I'm surprised that Dolby approved the implementation given the oversights and encoding quality.
> It's a consumer-level encoder, and if you look around this forum I think you'll find very few posts about audio quality, which would seem to indicate that Encore provides acceptable audio quality for most users. Cases with audible clipping can occur if the input signal is too high...keeping your audio signal around -6db should eliminate any clipping.
I don't buy into this whole argument about "consumer-level" and "professional-level". What is the exact difference? Dolby's code is constant across all licensed encoders, so any differences in encoding are the result of an implementation difference, and that's Adobe's fault, not Dolby's.
Audio signals are audio signals. Why do I have to keep my audio from peaking above -6dB with the Adobe encoder? I can take audio whose peaks go all the way up to 0dB and encode it with the Sonic Foundry encoder with no problem -- no clipping, no volume pumping, etc. Not so with Adobe Encore's implementation.
@Neil Wilkes:
> As far as Dialnorm goes, again I say it is pretty meaningless in a stereo file.
Dolby's encoding guidelines documents seem to say otherwise. In my readings, it seemed pretty clear that the decoder must have the dialnorm parameter set to the LAeq level of the dialog in the audio regardless of channel configuration.
> I suppose, although as long as the stereo mix is actually set up correctly there is no need to invoke DRC. The only time DRC would be needed on a stereo file is if the thing is too darn loud.
I have to disagree with this. There is a LOT of material that can benefit from DRC, both soundtracks that contain a large dynamic range (explosions to whispers), and soundtracks that have small dynamic range (speech). DRC doesn't have anything to do with the overall volume level of the soundtrack, but the dynamic range of the soundtrack. If the soundtrack is too loud overall, that's not a DRC problem, that's a level problem.
> In a properly balanced stereo file, there is no need at all for DRC or Dialnorm. There is no centre channel containing dialogue, just a phantom centre, so what are you going to reference it to, please? How can you attenuate the left/right channels with reference to the centre channel dialogue when there is no centre channel present?
Just because the dialog isn't isolated in the center channel doesn't mean you can't use it to set the dialnorm parameter. Plus, the decoder doesn't attenuate the left/right channels with reference to the center channel, it attenuates the entire soundtrack on playback.
Your quote from Dolby labs is very correct. Following that procedure ensures that the decoder, when it applies attenuation based on dialnorm and applies DRC will work as intended.
> Additionally, it is not referenced to average RMS either. RMS is close to the correct way to measure, but not correct.
That is true. However, I don't have any equipment to measure LAeq directly, so RMS of a dialog section of my audio will have to do. I do know this: When I applied to Dolby for logo usage on my DVDs, they requested samples of my DVDs for approval of my methods. My first submissions (where I didn't bother with dialnorm & DRC) were rejected, and Dolby sent me a letter telling me such. After I produced further DVDs using my method in my Doom9 post and resubmitted the DVDs to Dolby, they were approved. I can only conclude that my method, while not perfectly accurate, is good enough to qualify for Dolby's rigorous standards.
The bottom line is that I feel I have enough evidence to conclude that the DD encoder implementation in Encore is substandard. If you or anyone else feels it meets your requirements, then use it. But I for one will not allow a single DVD to go out from my company with audio encoded with this encoder.

Can't stream Dolby Digital movies from iTunes to Apple TV 2 since iOS 4.1

Has anyone the same problem?
Since I updated Apple TV to 4.1 it's not possible to stream movies with Dolby Digital sound to Apple TV anymore. When I try to start playing the movie I get this error message:
The operation coulnd\U2019t be completed.
(BackRowErrors error 326.)
This problem didn't appear on iOS 4.0. Videos with stereo sound still work, so I think it has something to do with the Dolby Digital. I encoded the videos using Handbrake.
Thanks for any help!

I was having the same error. I switched Audio Language to default and Dolby Digital to 'on' and I finally can see the video, but with no sound...
I tried MKVTools and Handbrake, AC3 passthru for audio on both, iTunes plays nice, but Apple TV doesn't. Any other solution?

Dolby Digital Live

Currently there are very few solutions for those of us that want true digital surround audio in our games. It's sad to say but the best in gaming audio usually comes from console systems because they are typically hooked up to home entertainment systems with spdif digital outs. So just like when you listen to a movie in Dolby Digital 5.1, you get great sound.
Now in the PC world, most games either don't support Dolby, or use some other forms of analog surround.
Dolby came up with a solution, which more games are starting to support. They call it Dolby Digital Live, it's basically a way for computer gamers to get true digital surround audio via a spdif output. The catch is, you have to have a sound card or motherboard which includes Dolby Digital Live.
From the research I've done, it seems the Mac Pros include what Intel calls their High Definition Audio solution, which on most chipsets is also known to include Dolby Digital Live, in this case the ACL880 chipset provided by Realtek should contain DDL.
My question is for those with their Mac Pros, spdif speakers, and XP installed. As mine is still on order, I'd like to find out if this is working. You would need to have a set of 5.1 speakers attached via the optical out of the Pro, and using the correct Realtek drivers under XP, run a game tagged with the Dolby Digital logo, such as Ghost Recon: Advanced Warfighter.
So basically if it works, you should be getting 5.1 surround and some really nice audio.

Hello Zacabeb,
I understand you are wondering if you can use the Dolby Digital Live on your HP Pavilion 500-205eo Desktop PC. According to the HP Pavilion 500-205eo Desktop PC Product Specifications your audio is the Integrated IDT 92HD73E Audio. I am providing you with the 92HD73E Datasheet, which on page 2 lists Dolby Digital Live™ (DDL) as supported. This being said to enable the Dolby Digital Live in Windows 8.1 I would advise you to ensure you that have downloaded and installed the IDT High Definition Audio Driver.
Please re-post if you require additional support. Thank you for posting on the HP Forums. Have a great day!
Please click the "Thumbs Up" on the bottom right of this post to say thank you if you appreciate the support I provide!
Also be sure to mark my post as “Accept as Solution" if you feel my post solved your issue, it will help others who face the same challenge find the same solution.

Titanium Dolby Digital - Windows Volume Controls Not Function

I am extremely happy with the Titanium because it finally elminated the 4GB Snap-Crackle-Pop issues I've been having since I owned this motherboard.
However, I've noticed that when I enabled Dolby Digital encoding over an optical output the master windows volume controls and muting do not affect the audio output at all.
Using the master windows volume controls with the analog or unencoded digital optical outputs work fine. It is only when using Dolby Digital encoding that I see this strange behavior. In-game and application-level volume controls & muting work fine; it is only the master windows volume controls that are 'ignored' when using Dolby Digital.
I'm still happy to see Dolby Digital encoding on this card, and very pleased that I'm using 4GB now without crackling in games or during music, but hopefully this Dolby Digital issue can be fixed.
Have any other users observed this odd Dolby Digital behavior?

Unfortunately (for me) the two of you are correct and windows volume controls have no effect in Vista.
Auzentech has this on their FAQ:
Q : After installing the sound card and connecting it to my surround sound system using S/PDIF output, keyboard and Control Panel adjustments to Volume and Balance either do not work or have minimal affect. Is that normal
A : With Digital Audio output, output levels are controlled by the wave volume settings. Multimedia keyboards and remote controls only adjust the master volume. The third-party application "Volume Tracker" corrects the situation by linking wave volume and master volume. Volume Tracker is compatible with Windows 2000, XP and Windows Media Center.
I also found this article:
"Another direct consequence of transmitting a compressed audio signal instead of an uncompressed audio signal (more commonly known as PCM) is that the volume of that signal cannot be modified once it has been encoded. Because the bits in an encoded signal no longer directly correspond to the volume of that signal, it is impossible to increase the volume until it is decoded. This explains why your PC cannot control the volume of your sound when you are using Dolby Digital or DTS as the output. The connected device will be the only place where the volume can be changed."
http://windowsvistablog.com/blogs/windowsvista/archi've/2008/03/04/using-s-pdif-to-send-audio-from-your-pc.aspx
So it would seem that this behavior is not only intended, but apparently unchangeable in Vista. In XP there is a utility (Volume Tracker) that can fix this, reportedly. This utility has no effect in Vista.
