ALC650 Optical 5.1 Output

Hi, I'm at a friend's house for 24 hrs. and he has a pretty sweet HT setup. Nice micro-mirror projector and surround sound. Well, his surround sound receiver's got an optical in and the onboard audio (which I've always used fine, but only analog) has an optical out. So why not try it, right? Well, I only get 2 channels. In soundman, clicking on subwoofer, center, or either rear channel produces nothing. Other inputs to the audio system do produce 5.1 sound. I haven't dealt with surround sound much at all, but I've had the analog rear/sub work a whlie ago.

So does anyone know how to configure my computer for 5.1 optical output?

Specs:

ABIT KD7-RAID (KT400)
- Realtek AC'97 ALC650 Onboard Sound
OC'ed 1700+
Radeon 9500 (if it matters)
512MB RAM
Windows 2000 SP4

    Is the receiver in 5.1 channel mode instead of Stereo mode?

    Will double check.

    Came across this from NS, and a friend has confirmed it...
    Though the downside to this is you can only use the SPDIF for multi channel gaming if you are using an nForce motherboard, as SPDIF cant only output games in stereo, but if you use an nForce board, it encodes the multichanel audio into a DD signal which then gets split back up by your decoder.

    Just wish there were some soundcards that did this.....

    Hmm... I'll try streaming something already encoded (if I have anything).

    Receiver really doesn't make it clear what mode it's in.

    Playing a movie, stuff is coming out of the rears, although they're a lot quieter than everything else.
