Hi everybody:
i came hear as the last resource ... i have tried
with alsa mailing list, and nobody answered me ...
I installed this driver(kernel 2.6.0-test2) and
compiled all the alsa libraries.

the rear channel, and the center/lfe channel.

i have tried with
alsaplayer -d hw:0,1 but the sound stills go out in
the front channel(only).

I have the exact same problem with the exact same card.
Rear/center channels are dead unless I duplicate front.
Has been there since before the 2.6 series.
