sound not working

I'm getting these system messages on boot:

Please try dxs_support=5 option
and report if it works on your machine.
For more details, read ALSA-Configuration.txt.

Disabling IRQ #12


and here's what I have in modprobe.conf:

alias snd-card-0 snd-via82xx
options snd-card-0 index=0
install snd-via82xx /sbin/modprobe --ignore-install snd-via82xx && /usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-via82xx { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-via82xx

This is a Fedora Core 4 system, 2.6.14-1.1656_FC4 kernel.

Any suggestions?
