ATI SB600 Azalia
From MEPIS Documentation Wiki
This sound card requires some editing of the /etc/modprobe.d/snd_hda_intel file. For convenience sake, I have it listed as a command to be run as root
cat /etc/modprobe.d/snd_hda_intel | sed 's/option snd-hda-intel position-fix=2/#option snd-hda-intel position-fix=2/g' > /etc/modprobe.d/snd_hda_intel
Alternate Way:
1. Open up /etc/modprobe.d/snd_hda_intel in a text editor as root.
2. find the line that reads option snd-hda-intel position-fix=2
3. remove the line or add a # before it
