Can you post the output of lsmod as well? The output you posted was the output of what Knoppix has detected on your PCI controller, the lsmod command will output all the "modules" that are loaded with Knoppix - "modules" are required - like drivers in Windows - to "understand" how to communicate with some hardware, like your audio / sound card. Some modules, in the case of sound servers, can "knock out" other sound servers modules, and the outcome is, no sound.
