I have been using MDK 9.1 for a while and just installed knoppix 3.3. The default sound driver did not work and I had no sound. I rmmod the old driver and then installed the alsa driver by modprobe snd-via82xx I now have sound, but when I reboot, the system reverts back to the default driver. How can I make the driver change permanent? I ran "update-modules" but that didn't do the trick.
