Hi, I have a SB Audigy ES which is connected to my 5.1 home cinema system through Coaxial S/PDIF.

I have tried all different modes on the PC and on my Receiver and i can ONLY get stereo out from the audigy:mad:

Is there any reason why i cant feed Dolby digital out from the audigy?
 
S/PDIF is not Dolby Digital or DTS. It is decoded matrixed sound. When you have a DVD player or reciever with DD or DTS decoders, it takes the raw signal and converts it into S/PDIF.

There really no DD or DTS ENcoders out there. The only way to pass non-decoded audio to the reciever is by watching a movie or listening to music already encoded in DD or DTS and setting the audio cards digital output to bitstream instead of PCM. That will pass raw signal and let the reciever sort it out.

Are you trying to watch movies or trying to listen to music? If you are trying to listen to music, then you are trying to distribute 2 channels of audio into 5.1. To do this you need to set your reciever to run Dolby ProLogic II or an equivelant. If you read the user guide in your reciever, it will tell you what audio modes activate which speakers.

I just read the product specs for that card and you can enable bitstream transfer. You want to do this. You want all of the sound processing to take place with the unit driving the speakers. So enable bitstream output on your card, make sure your reciever is running in ProLogicII (for 2 channel stereo), and play with the reciever settings. Be carefull tho. If your reciever does not handle DTS and you watch a movie and turn on DTS while the card is in bitstream still, the noise you get out of your speakers may be harsh enough to damage them. This only happened in older systems, as most recievers now handle DTS, but I don't know how old yours is.

btw: what reciever is this we are talking about?

Well all i wanted to do was play my games in Dolby digital.

I do and can play my mp3's and everything else i want in Dolby pro logic but its not as enjoyable as Dolby Digital:mad:

Also my Receiver doesn't support DTS and a few times the thing has blast loud levels of white noise at me:eek:

So to get true 5.1 audio out i will need to feed 3 jack to RCA cables out to the 6 Channel AC3 input on the receiver?

Thanks for the Help:)
 
Assuming your game outputs sound in Dolby Digital, I would just switch the optical port to bitstream mode instead of PCM and let your reciever do all the decoding. If the game is putting out sound in 2 channel stereo, then it should be processed just like your mp3's. If the game is 2 channel audio and your card is using something like EAX to force 5.1, then you might have to run component audio to the reciever
 
Well i assume doom 3 outputs Dolby digital.

The only way Ive ever been able to feed Dolby digital out from the audigy to the receiver was by using WinDVD 7 and a DVD movie:(

All the other mp3's/games and other sounds the audigy has just been producing 2 channel stereo from the digital out. Which then my receiver has transformed into Dolby Pro Logic:(

Looks like the only way to get true 5.1 audio must be by using component audio:(

O-Well Thanks For Ya Help:)
