Hi:

I have a Asus A7v 333 with a integrated sound card CMI 8738.

if a have xmms i can't play another sound with aplay or gaim, etc.

My Kernel is 2.6.1-1.61

# My /etc/modprobe
# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-cmipci

# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-cmipci

#--- OSS compatibility alias
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

This could be a ALSA sound module limitation. You may want to try ripping out ALSA and switching to OSS, for testing purposes, or just bite the bullet.

if you have several soundcards, look /proc/asound/cards for correct one
in pcm "hw:0,0" line.

that's very neat guide foolish :)

btw. in 2.6 kernels,, you don't need to have alsa-driver package installed if have
built it as kenel module(s). BUT you need to run MAKEDEV.snd which is found from
/usr/src/*kernel source here*/scripts/ to make it work.

script doesn't seem to be run automatically after kernel installation..
