Jean-Francois,
Yes, most of the channels are unmuted. BTW, if I switch on "Spread
front to surround" in alsamixer I am also able to hear on 4 speakers, but it's the front sound replicated on rear.
In the next days I'll try to extract an AC-3 (5.1) audio track from a DVD of mine for you to test.
May I ask what kernel/alsa versions are you using? Did you set up any particular ~/.asoundrc or /etc/alsa.conf?
thanks,
raffaele

Has anybody had any luck getting more than 2 channels out of the above southbridge?
My system: Athlon64 3000+ Asus k8v se deluxe (via8237 southbridge + AD1980 codec) kernel 2.6.9-r14 (using gentoo-dev-sources for amd64) via82xx alsa driver IceWM (no KDE/Gnome)
Stereo sound is ok, but I can't get surround channels to work. Electrical connections and volumes are ok, because if I select "Spread front to surround" or "Exchange front/surround" from alsamixer I get (front) sound from surround speakers.
I've tried the alsa included in the kernel, and the more recent alsa-driver 1.0.7, no difference.
I've tested it with $ mplayer -channels 4 (or 6) dvd://1 $ aplay -D surround41 file.wav
Any hint would be greatly appreciated, I ruined my fingertips googling for an answer...

I have the same chipset but with a shuttle XPC. Did you unmute most of the channels in the alsamixer ? Right now all of my 4 speakers are playing music. I can't say it's surround but at the very least I'm sure it's duplicated. Maybe by unmuting the right channel it should be fine. If you have a true suround sound file to test I could give it a go. Just send it to my gmail account.
Hopes this helps
