Yo!

I'm trying to get my sound card (Audigy) to output a digital signal to my surround sound amp. I've done this before using media player and SPDIFER and it worked great, but with the same software this time (after a re-format) I can't remember exactly how I did it. I'm using the 3.5mm SPDIF/COAX output into my amp but all I ever seem to get is the PCM light but no DD or DTS on my amp and all my encoded films are coming out in pro logic which isn't right.

Any ideas?
 
I don't think any Audigy's yet support Dolby Digital Live, unless the newly announced products are available [and I haven't checked]. So the only way you will get the DD or DTS signal is to play a media file or DVD that has the audio encoded that way. Otherwise Pro Logic is the fallback.
 
yeah I know they won't encode DD/DTS. But my problem is that when I try to play a DD encoded file, I get only pro logic or stuttering hiss. Do you use this method? What software/codecs/plugins/settings/media player do you use?
 
Whatever codec you are using for DD/DTS you need to set it to output via spdif. I use MediaPlayerClassic and AC3Filter and in AC3Filter properties is a "use spdif" check box which must be enabled in order to passthrough DD/DTS.

Otherwise using just MPC while a movie is playing, right click the video - filters - AC3/DTS Decoder and click on it. In the properties box that appears tick the options for "spdif passthrough".
 
I'm using AC3 filter too with MPC. I'm just trying out a ac3/44khz/5.1 song file which just gives me either stuttering hiss or a reboot :(

Have tried all various options in spdifer and ac3filter to no avail
 
XP SP2, why?

Also, why does it show '4/4.1 Surround sound' as my only speaker choice in the windows sound control panel?

If it was under Vista I had something for you to try but since its not, no bother.

It shows 4/4.1 as I guess its detecting your sound card as only being able to output 4.1. Doesnt matter what you select here when outputting over digital as you will only ever get 2 channels output from the Audigy unless its pre-encoded as AC3/DTS.
