yeah all models of soundblaster work but the x-fi AFAIK.
i have an audigy 2 ZS, works perfectly in knoppix, **** small linux, debian, all out of the box.
even the front live!drive and optical outputs work, all i need to do is add a line to /etc/modules and the IR receiver on it works. the only problem is that when i plug headphones in, the other outputs dont turn off, they do in windows... whatever i dont even care
oh and btw this is the linux forum and i cant even say the name of a distro hahaha
