Absent Dolby Digital[AC-3] Decoding feat

Ques :
My sound card Sound Blaster Li've 5.. Model no. SB Li've [A400].. Problem is Dolby Digital [AC-3] feature absent in Surround Mixer/Speaker/Setting dialog box. Pls tell me how I get that feature. I use original software. Surround Mixer Version is 2.00.53
Ques 2 :
My Speaker Creative Inspire 5. 5200. How can I hear Dolby Digital and dts sound?
Ques 3:
If I use Audigy 2 Zs and Creative Inspire 5. 5200. Dolby Digital and dts sound can come through my speaker?

Q: From the description of you soundcard of the Creative website, it looks as though you should have dolby digital decoding capability, but I'm not sure why your AC3 option would be missing (my option is in the advanced playback settings).
Q2: If it turns out your card is not capable of decoding AC3, then you can use a version of PowerDVD or WinDVD with Dolby Digital/DTS decoding capability (not usually available in the free versions). This will let you get DD/DTS using the analogue connections to your speakers.
Q3: The Audigy 2 can decode both DD and DTS so you will be able to use the analogue connections to your speakers to get 5. surround sound.

DTS-610 connection to Dolby Digital Receiver without DTS feat

Hi,
I have a JBL ECS 333 sound system (amplifier + speakers) with Dolby Digital 5. support and digital inputs (optical + coax.). It has not DTS label on it - just the Dolby Digital! Will the DTS-60 work with my system.
Thanks,
roku

roku,
I'm afraid you will need a receiver/device that's capable of decoding DTS in order to work with the DTS-60.

Suggestion :x-fi dolby digital decoding vs logitech 680z optical decod

high guys , i got the xfi platinum because my set of speakers , logitech 680z has dolby digital and DTS decoding trough spdif blow by , and i also noticed that the x-fi has built in decoding .
im split in half because i think the sounds quality will travel clerer trough an optical cable than analog cables to my set of speakers , but i think the card would do a better job decoding in and enhancing the sound with the crystalizer (although dvd sounds should be 24 bit anyhow) and on more updated drivers.
however the logitech its not a full home teather system , is barely a high end computer speaker system that sounds great here is what it looks like http://www.logitech.com/index.cfm/pr...CONTENTID=9486
so what is your take on it ? dolby digital blow by with optical cable and external so so decoder , or xfi decoding with with the loss of analog cables ?

alexs3d2 wrote:The site you linked to is actually for the newer Z-5500s. The best way to go forward is to test it by yourself and select the mode that sounds best. If it wasn't for the Crystalizer I would say to allow the external amplifier to do the work. Don't worry about the analog cabling, it shouldn't change your sound or add noice in any conceivable way.
first of all thanks for your opinion .
and the link i provided is because they dont sport the z680s on the website and the 5500 are the direct succesors , however they are the same decoder , save the nicer polished look and the bigger woofer ,dual speaker satelites and extra watage .

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
- Klinke-Mono - Chinch-Stecker ( Stecker –Stecker ) ( Favorit !! )
- Klinke-Mono auf Chinch-Mono ( Stecker - Kupplung ) + Chinch-Verbindungkabel
( Stecker - Stecker )
- Klinke-Stereo auf Chinch-Mono ( Stecker - Kupplung ) + Chinch-Verbindungkabel
( Stecker - Stecker )
Das digitale E/A-Modul ( Digital I/O – Modul )
Die Verwendung von optionalem Zubehör Digitales E/A-Modul ( Digital I/O-Modul ) bietet die Möglichkeit der direkten Verwendung eines S-PDIF Verbindungskabels und stellt zusätzlich zum koaxialen Anschluß einen optischen Anschluß ( Toslink ) bereit. Die optische Verbindung kann wie oben beschrieben zur Vermeidung einer Brummschleife hilfreich sein.
Des weiteren wird ( abhängig von der Ausstattung der Soundkarte *** ) ein digitaler Eingang über das E/A-Modul bereitgestellt, der Eingang ist ebenso wie der Ausgang in optischer ( Toslink ) und koaxialer ( S-PDIF ) Bauform ausgeführt.
Achtung !!
( *** Bei Karten der SB073X-Serie verfügt diese Buchse nicht über die Digital-In-Funktion !! zur Unterstützung des digitalen E/A-Moduls )
interner S-PDIF E/A-Anschluss ( für Geräte der SB073X-Serie )
zum Anschluß einer Decoderkarte oder externer Decoder bzw. Lautsprechersysteme mit digitalem Eingang ist ein entsprechender Adapter erforderlich
Bei einigen Modellen ist eine Dekoderkarte im Lieferumfang enthalten bzw. in einigen Regionen als Zubehör erhältlich
Front Panel-Sockel (für Geräte der SB073X-Serie)
2 x 5-poliger Front Panel-Sockel nur für Verbindungen mit einem Intel HD Front Panel Audio-Standardsockel (nur Geräte der SB073X-Serie) Intel Front Panel Audio-Kabels (separat erhältlich)
Anschlusskompatibilität
Ausschließlich Intel HD Front Panel Audio-Standard
Nicht kompatibel mit AC97 oder Intel-kompatiblem HD Front Panel Audio
Einschränkungen
Wenn neben den hinteren Mikrofonen auch Frontmikrofone angeschlossen sind, werden die hinteren Mikrofone automatisch deaktiviert.
Sound Blaster X-Fi E/A-Konsole
Auf der Rückseite Ihrer X-Fi-E/A-Konsole* befindet sich eine sogenannte DIN-Buchse. Um die Funktionen für eine integrierte Lautsprechersteuerung zu nutzen, können Sie an diese Buchse ausgewählte analoge Creative-Lautsprechersysteme anschließen, die über eine Kabelfernbedienung oder eine Audiokonsole verfügen.
So können Sie beispielsweise über den Master-Lautstärkeregler Ihrer X-Fi-E/A-Konsole die Lautstärke der Lautsprecher regeln oder die Lautsprecher stummschalten.

DTS and Dolby digital support in Vista for Audigy 2 ZS Video Editor

Hello, I own a SoundBlaster Audigy 2 ZS Video Editor with USB connection and would like to know when will be available a drivers for Windows Vista and Windows 7 where we have full support for using the Dolby Digital and DTS decoder, I mention because it seems that?this card is forgotten about the update of drivers and is a pity that it is?lack of the support.
Greetings and thanks in [email protected]

Sorry for not replying - have been away for the past few days.
Ok, so I go to Creative Device Control, and on the PCI/USB tab I've changed the sampling rate to 48khz.
It was previously at 44.kHz
The bit depth is still at 6bit
Now the problem seems to be solved.
The problem was only with the output from the device. And now there are no skips!!
Excellent!
Why has that solved it though?
I've read on other forums (head-fi) that the audigy cards do not run at 44.kHz nati'vely so the sound has to be downsampled.
Is that skipping an artefact of that downsampling process?
Will having that set at 48kHz, but recording to a 44.kHz 6bit wav file theoretically reduce the quality of the recording - compared to having it set at 44.kHz and recording a wav at 44.kHz?
On the SPDIF tab the input sample rate is shown as 44.kHz - as that's what is output by the DAC in my minidisc deck.
But when I changed the sampling rate on the PCI/USB tab, the SPDIF output sampling rate also changed to 48kHz.
This means if I wanted to record from the optical output, whilst also recording to the computer, and that device only supported 44.kHz - I can't do that?
You listed some main reasons to the truth, why Creative SB cards are not very popular on serious use (DAW). I.e. need for resampling. X-Fi's in creation mode are (least said to be) the only ones not resample everything.
There is a setting for "Bit-Accurate-Recording" (digital modes only) --> have you tried if that works on your recordings?

Decode Dolby Digital from optical inpu

Hi,
I bought SB X-Fi Extreme Audio PCIE. I know it'sdoesn't have?any hardware supported features, but maybe there is some?software way to decode Dolby Digital send throught optical cable to SB input ?
Second question - which SB model should I buy to get this working ?

I don't think the Audigy 2 NX has decoding hardware onboard, it uses a driver based decoder therfore all decoding is done by the computer. The Extigy is different, it has and actual onboard decoder so it can be used as a stand-alone Dolby Digital decoder, not requiring a computer to operate. I'm not sure whether the NX can decode AC3 from an external source or if it is limited to decoding signals originating from the computer (i.e DVD or AC3 file).

Searching for sound card, which decodes Dolby Digital from S/PDIF-IN

As I wrote in the topic headline, I'm currently searching for a sound card, which decodes Dolby Digital from the S/PDIF input.
I.e. a DolbyDigital signal comes from an external device (here Set-Top-Box/Media-Recei'ver) and the sound card should send the signal to my analogue speakers.
Currently I have a Creative X-Fi ExtremeMusic, this card does not support this.
And yes, I read the thread "Digital Connection...".
Thanks for any replies!

HRe: Searching for sound card, which decodes Dolby Digital from S/PDIF-INE I'm still doing some research on this topic, although I'm already searching for 2 years now with no real solution. Several people say, that I can do that, what I described in the first posting, by using an I/O console from Creative. But Creative (support) says, it is impossible at all, they don't have any products, which can do this.
Can anyone tell me, whether it's possible or not? Important fact: I use Windows XP, not Vista. And I don't want to use modded drivers. I want to use the latest official ones.
The new soundcard "Creative Sound Blaster X-Fi Titanium Fatalty Champion Series" has an I/O dri've. If I have this, can I decode DolbyDigital from S/PDIF-IN, if I plug the optical cable into the soundcard? Because this console seems to have no optical input.

SB Audigy 2 ZS - Conect to Teac Power Max 1500 with external decoder Dolby Digital Decod

I can't have de digital sound of my soundcard, beacause my speaker systems don?t have that type of cable (for digital sound, my system have a coaxial and optical.
How can ? conect my speakers (wich have an external decoder) to the digital out of de SB Audigy 2zs? I have buy de Creative Digital I/O Module, that have coaxil and optical output, but this not work in Audigy 2 zs....(:
Have I buy another speakers? this speaker?s are great, and I have my dvd conected to him.
Tks.

There's a digital output on the card itself. 'tis the farthest one from the motherboard I beli've.
What you erally need is a cable like t his one:
http://www.needledoctor.com/Sony-RK-...=2&category=92
Plug the mini-plug end into the soundcard and one of the outputs ( the left channel I believe ) will have the digital output.
You will only get surround sound via the decoder if when playing back pre-encoded DD/DTS content like DVDs. Games and stuff will playback in stereo when connected digitally as SPDIF only supports compressed multi-channel bitstreams or uncompressed 2 channel audio. No Creative card at present offers real time DD/DTS encoding ( there're other cards which do which support Dolby Digital Li've! or DTS Connect. ) Creative have a DTS encoder called the DTS-60 which can take analogue signals from the soundcard ( stereo mini-plug x 3 ) and encode it to DTS for output via a coaxial or optical SPDIF in real time. I've never used the DTS-60 and can't comment on how good it is. Also note that the Audigy 2 ZS has weak bass redirection if using the DTS-60 and the 60 lacks bass redirection of its own so you could very well end up with a 'bass-less' signal if you're connecting to small speakers, unless your decoder has volume controls for the subwoofer.Message Edited by nvidiot on 09-27-2006 0:32 PM

Vista ultimate x64 any chance to get decoding of dts and dolby digital for audigy 2 zs platinum

hello,
i need the support of deconding dts or dolby digital for my audigy 2 zs platinum pro.
is there any chance to get this feature back in vista ultimate x64?
i hope anybody can help me.
thanks for all
steffen

According to Creative, Vista no longer supports the decoding of Dolby and DTS at the driver level, so no, that feature proabably won't added back in the future. It is gone for all the Creative cards.

Live! 5.1 SB0100. Can decode Dolby Digital 5.1 (AC3) from S/PDIF-

Hi,?i have a Sound Blaster Li've! 5. model: SB000. This can decode AC3 from S/PDIF IN and out to analog outputs?. My idea is connect Xbox 360 to S/PDIF IN and decode Dolby Digital to analog outs. Thanks.

Nope. The original EMU0K chip always had resampling enabled on S/PDIF input so that if there was any clock drift at all bits could change and damage the AC3 encoding. The EMU0K2 (Audigy) chip was changed to somehow allow bypassing the core clock so the S/PDIF sample values could get into memory without alteration.

¿Does Audigy 2 NX decode Dolby Digital 5.

Hi,
I've purchased an Audigy 2 NX to connect my xbox 360 via optical sound wire and get Dolby Digital 5..
The problem starts here, i've connected the console to optical In (in the sound card) and i've connected the 5. via standart jacks (the 3 typical jacks), if i set Dolby Digital 5. mode on the xbox 360 i don't get any sound, but if i set it to Stereo Digital it sounds but only in 2. mode (front speakers).
The dolby digital led in the sound card never works, it's always off, it suposes to be on when it detects a Dolby Digital Input (like the 360 one's) but it always remains off.
How can i decode Dolby Digital 5. via optical in? In the sound card spec's says that this card is able to Decode DD 5. and 7., but it seems to be a lie!.

this soundcard does not decode from external source...so it won't work this way.

Audigy nx dolby digital decod

I have one of these units for my acer aspire laptop, i have NEVER got it to decode the dolby digital from a bought dvd yet, it doesnt even show the dolby light.. all the speakers test as o0k with the test tone, but put in a dolby surround dvd and all you get is two channel stereo.
So much for 5: surround sound, not much use of half your speakers are redundant.
Anyone else encountered and / or SOLVED this id really appreciate any info you have

Sorry, for some reason I suggested selecting 'SPDIF Pass Through' :smileyindifferent:. Actually if you are using analogue speakers, this option should be off. Just selecting SPDIF output in the DVD software should work.

Decoding Dolby Digital via Optical

Can anyone tell me if it is possible to decode the digital signal from my satellite receiver via the optical in port on my Audigy Platinum? I hooked it up and all I got was basic surround, and yes, I was watching a movie on the receiver that was being broadcast in dolby digital.
Thanks for the info...

What do you mean "Basic Surround"?
As far as I know, it is possible with the Platinium dri'ves. Provided your receiver is sending RAW Un-decoded Dolby Digital signal to the dri've.
If it is already decoded, the signal being sent through the optical cable will only be received as Stereo..if I'm not mistaken.
Someone else with hands-on experience will have to give you a better confirmation, as I dont have a Platinium dri've before. But I know its possible.

How come I get Dolby Digital decoding, CMSS, and EAX effec

Perhaps this is related to the fact that I use either headphones or 2. speakers. The info on the Vista beta driver says I'll get no dolby digital, CMSS, etc.
But, in PowerDVD I set to SP/DIF and the Creative decoder gives me the DVD audio fine! I turn on CMSS 2 and it expands things nicely for my headphones just like on XP.
Same with the Advanced EQ EAX settings and CMSS 2 with mp3 listening with headphones. The different settings all work, and have worked even before the Vista driver came out when I was using the XP driver.
Is it just the expansion to 5. speakers that doesn't work yet? Because the headphone listening effects seem to not only work, but music and DVD's actually sound better than on XP!
Further info: Vista RC Build 5728 32-bit, Audigy 2 ZS Platinum, Vista Beta Driver.
The driver install went perfectly except for some error messages on the first restart about driver access.
The major improvement for me regarding the Beta drivers over the XP ones is that Creative Soundfont Manager and Soundfont midi now works. I custom installed the Soundfont Manager, AudioHQ, and found that for some reason the DTS/Neo stuff gets installed along with System Info and Registration even when not selected. I left out everything else and did not install MediaSource Player.
Audio Console is able to control all the stuff in it. EAX Control in AudioHQ doesn't seem to work properly but Audio Console can switch between the preconfigured settings and the changes take effect fine.
Just no EQ. I tried installing it and it wouldn't run. That's how I found out the DTS stuff is installed. I noticed it when uninstalling the EQ.
The Advanced EQ in Audio Console works fine though.
Apparently the Vista Audio improvements help out the sound quality. At least for mp3 listening and DVD's, things are sounding quite a bit better than they do on 9x or XP.
Now if we could get a new driver/software package from Creative. Heck, they did it for Li've/Audigy shortly after XP came out (redesigning the whole package). Maybe they'll actually make us happy and give us a similar easy to install package that all works together.
I'm sure this won't happen until after Vista final comes out, but I wouldn't be surprised if they have this in mind.
It's just frustrating during the beta period. Especially for those that haven't gotten good (or, any) results.
It's weird. I know I've been lucky but nearly anything I've tried since starting to test Vista with my Audigy 2 ZS has mostly worked.

From what I've seen, the most of the problems with the cards are with the 64-bit drivers. My Audigy 4 also works with the XP drivers of the CD and Vista B2 drivers as much as they should. Many people don't realize that it is a beta driver, on a new OS (which is now in final development) so some things will and will not work. Also many people don't read readmes and such and still complain on things that where stated. Such as the Vista B2 drivers for the Audigy series
Known issues:
* Waking your computer from sleep or hibernate mode stops audio output. To resolve this, restart your computer.
* In this download, the Effects Amount slider in EAX is disabled.
* To configure your speakers, use Audio Console only. Configuring your speakers in "Audio Devices and Sound Themes" in Control Panel may result in loss of audio during playback in Windows Media? Player. To resolve this issue, close and reopen Windows Media Player again.
* This download does not support
o Dolby? Digital or DTS? decoding
o CMSS?-3D
o recording
o 6. speaker systems
All thats stated is pretty much what people are complaining. Though its stated what won't work, they may work due to its a general driver and not a specific driver. So some may have somethings working on one card, and not on the other.
