no sound with Knoppix 3.3

[windos_no_thanks]

Hmm, looks like there is another audio device present:

00:0d.0 Multimedia audio controller: Yamaha Corporation: Unknown device 1000
Subsystem: Yamaha Corporation: Unknown device 1000
Flags: bus master, stepping, slow devsel, latency 32, IRQ 5
Memory at cb000000 (32-bit, non-prefetchable) [disabled] [size=256K]

What modules are loaded ?
(do "lsmod > modules.txt" for instance)
