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.

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).

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.

¿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.

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.

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.

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.

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

ATV3 - I need to enable dolby digital for optical surround sound (netflix and home movies), but when I do this it stops audio coming through TV speakers

I have a cinema sound receiver connected to Apple TV via optical cable. When I have dolby digital set to Auto it doesn't come through as dolby digital when watching movies on netflix and iTunes (home movies).
If I set Dolby Digital to ON it works as expected, but the sound stops working through normal TV speakers (via HDMI). This is the same for netflix and home movies.
I tried 16 bit setting, but it made no difference.
Any advice on how I can get this working - meaning Dolby Digital always on for when I turn my surround sound on and sound through speakers for normal operation?
Obviously I can change the setting when needed, its just a pain.
Thanks in advance.

Hello everyone,
here is the friendly and signed driver installation method to enable Dolby Digital Plus in your Encore internal speakers only. This is not an official driver, there is no control panel for Dolby Digital Plus or various sound effects, but tested and has much better and richer surround sound quality as before with factory driver. I guess, this driver tweak can work with any Bay Trail tablet also.
How can you upgrade Encore sound drivers:
1. Download signed driver package and extract.
2. Open Device Manager.
3. Upgrade your Sound, Video and game controllers
- Intel SST Audio Device
- Realtek I2S Audio Codec
one by one with "Have a disk" method.
4. Double click enabledolby.reg file and add to your registry.
5. Restart, and enjoy better sound quality.
Thanks.

Set Dolby Digital for optical only, not HDMI?

Just wondering if there's a way to set the ATV2 to output Dolby Digital only over optical but not over HDMI? My TV doesn't support DD but (obviously) my 5.1 receiver does. If I leave the setting on "Auto" it just sends a stereo signal to both HDMI and optical, but if I turn it on to "On" then it works via optical but not over HDMI since the TV can't understand it.

I set up my TV as a monitor only and route all sound directly via optical to my receiver. I then muted my TV, and control sound via the receiver.

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.

Dolby Digtal via optical cable not work

Have an Audigy 4, recently bought a Digital I/O module as some searching lead me to believe that the Audigy 4 can do dolby decoding... (thinking about getting a PS3 and hooking it up to my monitor) Well, i've been testing with my PS2 and a DVD. With dolby off in the options menu I get stereo sound just fine, the moment I turn Dolby Digital on I get no sound whatsoever. The DVD i'm using to test got both Dolby Digital and DTS audio tracks and I made sure to select the dolby one.
anyone have a clue what's going on?

So creative lied then... Just lovely. the audigy 4 is supposed to have HARDWARE Dolby Digital...

Decoding Dolby Digital not available in Platinum

It's as simple as it gets, clean windows SP2 instalation with security updates.
There's no Decoder Tab in audio console and i don't get any sound in spdif on powerDVD when there's the dolby digital bitstream out logo. Anything that isn't dolby digital does play sound.
This is PLATINUM FCS (as in EXPENSIVE CARD THAT SHOULD HAVE BUILTIN DECODER like the original platinum), i got the FCS version after my original regular platinum broke down after 3 months.. and it had built-in decoding.. you're not going to tell me that this MORE expensi've (not much tho) card doesn't have. :|
Anyway, sorry about the ca
ps.
.. just that x-fi cards for the last months has giving me headaches despite the great features and sound quality.Message Edited by darthdan on 08-6-200703:3 PM

Well, checked the features in the product page... it seems it doesn't.. So i'll give this post an oportunity to let it all out.
How the heck does my bulk audigy 4 that costs about 7 to 8 times less has that feature and also how the previous platinum had the feature and this one doesn't?
Ok, so creative added the x-ram, like many games take advantage of that and like everyone has speakers to take advantage of that. I guess it's resources and marketing all the way.
Bottom line, considering the sound quality of the cards and features i wouldn't call them a rip off but some stuff really messes with regular clients.
I guess creative not having a serious competitor in the regular consumer market make's they more relaxed a bit. (But i may be wrong since im not workin for creative or inside of it to see how they work. I admit that possibility.)
Anyway, hope im not a bother and have a nice day.

Dolby Digital dropouts on Apple TV

I have the latest model ATV connected via HDMI to an Arcam receiver which can decode Dolby Digital via that cable. The ATV is connected to my network via ethernet but I get regular dropouts of DD sound – the sound disappears for a second or two and the amp shows a message '3/2.1 - EX off'.
This happens on Streaming movies over Netflix or playing iTunes content from my mac.
The file is not at fault as replaying it will often have the sound dropping out at different points in the movie and earlier dropouts will usually play normally. Itunes was downloading in the background but would this affect replaying of a movie file or the straeming of a netflix movie?

Probably not the case but do check all you speaker cables are secured properly - I once had random dropouts and one of the the centre speaker cables had come partially loose and a few strands were intermittently shorting with the counterpart causing the amp to shut down audio momentarily.
Personally I'd try a different HDMI input or cable if the Arcam has a separate input.

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.
