well, I'm trying to get my nForce4 board with an ALC655 working with
digital output to no avail. I pasted the above to /etc/asound.state
and am using the .asoundrc for the ALC chips. I've got an ECS KN1
motherboard.

I'm also using kernel 2.6.16, which someone mentioned doesn't work
with alsa? which could be since I can't seem to get analog audio
either...
anyone have any ideas?
