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.
When i play sound everything works great except for 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).

cat /proc/asound/cards

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.

Argh. Ignore confirmation of bug
Problem were some config settings and my ignorance.
5.1 seems to work with xine playing dvds - now have to figure out how to balance it correctly :)
