I have the same motherboard and i was facing same problem. after
searching through google and various linux-related site, I found two
steps to solve this problem.
NOTE: install alsa-oss, alsa-utils packages
1. edit: /etc/modprobe.d/alsa-base
Add the following line at the end of the file,
"options snd-hda-intel position-fix=1 model=3stack" (withour
quotes)
After step 1, force-restart alsa module and see if it works or not.
2. edit: /boot/grub/menu.lst
add "noapic" option at the end of the kernel options.
reboot the machine. everything should work fine.
