I have the EXACT problem!! I still haven't been able to use my "Audigy" driver for my card like knoppix said during boot, but once knoppix is done with loading hardware and what not at the bottom at the boot: prompt type "Knoppix alsa" it's a cheat code for audio. It uses my SB Live Audigy card for sound but I'm not sure if it's to it's full potential.

Hope this helps!!


Edit: I see someone has already told you while I was typing, lots help here!!!
