Optical Dolby Digital from 46SL412U

I'm trying to get 5.1 audio passed through my 46SL412U. My Xbox 360 is hooked up to my TV with an HDMI cable. If I run an optical cable directly to my receiver from my Xbox, then I get 5.1 audio. I have the output set to "Dolby Digital" in the Audio Setup menu but if I run the optical cable from the TV, then I only get PCM stereo. At the moment I only have one 5.1 device (the Xbox), but I'm getting a digital cable box and I'd like my TV to be able to forward the audio from whichever HDMI source is active to the receiver.
Any help would be appreciated.

"Dolby Digital" is selected but it's only outputting PCM? Sometimes there can be issues due to copyright, so usually I suggest connecting directly to the receiver. I can see how running it from the TV could be easier though. You might want to call technical support at (800) 631-3811.

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.

How to get Dolby Digital from ATV2 and iTunes Movies??

I have an ATV2 hooked up to my Denon 789 AVR via optical cable, and the HDMI hooked directy to my HTDV. My Denon is receiving the signal apparently as a PCM and thus, only receiving 2 channel. When I stream an iTunes movie from my ATV2, I only get Dolby Pro Logic II, and not Dolby Digital. When I go into the ATV2 settings and under Audio and Video set Dolby Digital from "Auto" to "On", I don't get any sound on my Denon 1910. Any idea what's going on?

Unable to open dolby digital from control panel in G510

Hi ,
When i try to open the dolby digital from contol panel i get this error.
in lenovo g510
Solved!
Go to Solution.

hi shanalikhan,
The error on the screenshot that you posted usually happens if the version of the audio driver and the dolby digital driver are different. Both of them must use the same driver in order for them to work correctly.
Try to:
1. Press the Windows key‌ +R, type appwiz.cpl.msc and press Enter. On the list of installed programs, remove anything that relates toRealtek Audio Driver and Dolby (reboot if necessary).
2. Delete the C:\Drivers folder Install this audio driver (windows 8 version).
Audio Driver (Conexant, Realtek) for 64-bit Windows
3. Open Device Manager > Sound, video, and game controllers and check if the High Definition Audio becomes Realtek High Definition Audio or Conexant High Definition Audio (this indicates that the sound driver is installed properly).
When the audio driver is properly installed, install the DolbyAdvancedAudio and the DolbyHomeTheater from the following path:
For Realtek:
C:\Drivers\Audio\Realtek\6.0.1.6957\PCEE4
For Conexant:
C:\Drivers\Audio\Conexant\8.64.49.0\DolbyGUI

More info:
Dolby Audio driver cannot start after upgrading to Windows 8.1
Let me know how it goes.

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).

TS3518 Dolby digital from Apple TV

This used to work fine before the last update. What did apple do for this not to work. I have HDMI out of my Apple TV into my surround sound receiver which decodes dolby digital. I have to turn off dolby digital to get audio. the whole point of using a surround recieve is to use dolby surround. There is no point of renting movies from Apple TV wiothout surround sound capabilities. Why is this not working?

My experience is the same. Loss of Dolby Digital 5.1 output. Amplifier (Yamaha) indicating "PCM" signal, instead of DD. So far, no acknowledgment of the issue from Apple.

Dolby digital 5.1 from mini port while in windows?

Hello all,
I'm running the most current of all software, and I'm trying to get 5.1 dolby digital from the mini port to HDMI? All I can get is 2 channel. Is it possible to get this to work? I'm using KM player and I'm certain this player supports 5.1 output. Any advice would be helpful. Do I just need to buy a toslink (optical cable) or is there a way to make this work?
Nate

As far as optical out goes, stereo sound from MP3s/WAVs/AACs etc, and stereo soundtracks seem to get converted by the Apple TV to a linear PCM type bitstream. Since Take 2.0 AppleTV can also output dolby digital 5.1 bitstream but does not need to do any onboard decoding.
Most amps/receivers that can accept an optical audio feed from a DVD player should do fine (certainly for the 5.1 DD). I would imagine if you are connecting via HDMI to the amp/receiver then you would have no trouble with any modern amps that support HDMI.

Dolby Digital Settings

With my system, if Dolby Digital is set to "On" in settings, I don't get any sound at all from Rented or Purchased movies from iTunes - however, I do get sound from Netflix, Youtube, iTunes music, etc.
Sound works in iTunes material if Dolby Digital is set to "Off" or "Auto."
I'm worried, however, that if a Movie is Streaming with Dolby Digital, the sound should be working when the Audio Setting is "On." Am I just getting stereo audio if the Dolby Digital setting is "Auto?"
Currently I am only running the HDMI Cable to the TV - no Optical Audio out or anything.

I think it's probably similar to my issue here:
https://discussions.apple.com/message/17926593#17926593
Rentals generally have either 1 or 2 audio tracks.
The first is stereo (occasionally mono), the second is the dolby digital surround.
I connect to the TV via HDMI and to the surround processor via optical.
In the past I'm sure I've managed to have sound from the TV (HDMI) or surround processor (optical Dolby Digital simultaneously).
I think what currently happens is this:
AppleTV 'talks' to the HDMI device and ascertains what it can support. Most TVs will not be able to decode Dolby Digital over HDMI. Receivers/amps with DD capability will.
So when the TV is connected via HDMI, and DD is set to off or Auto the TV gets the stereo feed (Auto selecting stereo as TV can't handle DD).
If however DD is set to On this forces DD through HDMI but the TV doesn't know what to do with it.
So in my situation I can either have it set for stereo audio over HDMI (Off or Auto) and optical, or DD over both (DD set to On.
Clearly I want the stereo track to go to the TV over HDMI and DD over optical (falling back to stereo if no DD track) so I don't have to fiddle in Settings each time I choose to listen through TV vs surround system.

Dolby Digital 5.1 Question

I used to have an Apple TV (Gen 1) that I streamed my ripped DVD collection to. I had create the files using Handbrake (AC3 Passthrough). Then, after a "patch" by Apple the Dolby Digital stopped working. Fed up, I sold the Apple TV in frustration.
Some time has passed and I've recently gotten an iPad 2 and I really like the potential of AirPlay. I am considering picking up the new Apple TV but only if I'll be able to play files with AC3 included. Can the new Apple TV play AC3 files either through the HDMI cable (preferably) or the optical cable?

The apple tv seems to be notoriously iffy about passing through Dolby Digital from non-iTunes bought material.
Since getting the ATV2 I have not been able to get it to work as it used to in the ATV1.
First problem was that you had to play a iTunes bought movie with DD which would then allow passthru to happen on all ripped material as well... weird but at least a work around. If you tried playing ripped material (from handbrake for instance) it would just fail unless you turn DD off or play an iTunes movie with DD first.
This week the ATV2 did another update and now even with DD on auto doesn't work for iTunes bought material. You have to explicitly turn it on for DD to work at all but then none of the ripped material will play any audio at all if it has a DD track.
Turn it on and iTunes will passthru DD from iTunes movies but ripped material won't. Turn it to auto and nothing with passthru DD. Turn it off and everything plays on PCM from AAC track (as expected)...
Seems a bit like we are going backwards here.
I'm starting to think Apple don't have any regression testing for this feature at all.
I read in another thread that apparently the trick is to set the DD track as disabled in the mp4 container and then it will work. I don't see why this is needed at all and seems very picky on the software's side. I still need to investigate this to see if it's true, but most tools out there will not do this and thus the material won't play on the ATV2 in surround. It a real bummer as that is my main reason for having it in the first place.
90% of my material is ripped DVD's and Blu-rays. I am forced to watch them all in stereo now or fall back to a DVD player...

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.

I would like to connect my Apple TV to my receiver using an HDMI cable and pass thru dolby digital. I do not have optical inputs on my receiver.

I want to connect my Apple TV to my receiver using an HDMI cable. This should allow me to pass thru high definition video and simultaneously decode Dolby Digital material with an HDMI connection from my receiver to my TV without the use of an optical cable (my receiver does not have an optical input). I am unable to decode 5.1 material and don't understand why this is not working. In the audio setting I have Dolby Digital output turned on.

Welcome to the Apple Community.
Are you sure the content you are playing has Dolby Digital.

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?

Proper 5.1 Dolby Digital using Optical in on Audigy 2 ZS

As of yesterday night, I have connected my PS3 to my Audigy 2 ZS via optical in, so that i could hear 5.1 from my PC sound system (Klipsch Promedia Ultra 5.1).From what i've heard somewhere (I don't know if it's true) you need audio to be in the bitstream format in order to hear proper dolby digital 5.1 when using an optical cable. When selecting the (PS3 MENU) Blu-ray optical out as LPCM, I've managed to get audio to all speakers (including subwoofer (doesn't sound like proper LFE emission)) but it'sjust sounds like stereo on each channel, not the proper discrete surround sound. When I set my Blur-ray disc optical out to bitstream (hoping to hear real 5.1) I hear no audio during the film (although somehow on one test i heard sound in the menu). How do i get my sound card to recognize and decode the bitstream format so I can hear dolby 5.1 or is an LPCM signal sufficient for proper 5.1 In the creative audioHQ, I have set the digital input to Dolby Digital/DTS SPDIF-in Decode. This is the only change I have made (on the PC)so far to hear 5.1 sound from an external device (I also got the sound card to recognize the SPDIF-in). Is there more I am supposed to do, or is it enough? Is the AC3 audio filter neccessary for my situation? For additional information, (In the above setups) i do not get audio for DVDs or games (these could be PS3 issues)?Any advice or information would be greatly appreciated?Thanks!

Here is perhaps a better reply ....
The only 5. compressed signal the Video Editor (or the NX) can play is one that originates on the host - via a DVD player like InterVideo or Cyberlink, or from Creative Media Source application - the digital stream is decoded in the driver and then sent to the external device. It cannot act as a stand-alone decoder box in which the signal originates from the S/PDIF jack.

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

{quote}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{quote}
In Bruges - in 5.1 works fine on my ATV with it connected to my AV receiver via HDMI
{quote}The soundtrack worked beautifully when sent via optical in full DD 5.1{quote}
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.
{quote:} 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{quote}
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.

5.1 Dolby Digital via optical cable in Mac Pro?

Hello!
I'm planning to get a new Mac Pro and I wanted to know if a Dolby Digital or DTS encoder is included to have 5.1 output with the optical TosLink cables.
I need this to connect the Mac with my 5.1 surround sound system because I wanted to watch DVDs using it.
If it only supports stereo sound in the standard version, do you have any recommendations to expand it to get the described feature?
Thanks for answers.

Hook up the toslink, set the output to digital in System Preferences>Sound, set the input on your 5.1 receiver and match the surround sound format in both the DVD movie sound prefs and the receiver.
That's it.
Remember to set the speakers in the correct positions from your sitting point or it won't work very well.
To test the surround sound I suggest the movie Castaway, where Tom Hanks is picking up Fedex boxes from the surf line. You'll hear the waves crash on the left, Tom walking towards you and coconuts falling on the right.
The toslink and a good receiver also makes your rips and iTMS songs sound great too.
Check out the Volume Logic iTunes plug-in as well, really makes the music sound great.
