[GLLUG] sound with Knoppix

I was trying out Knoppix 3.3 on a system with a Cyrix media GX processor. 
The audio chipset is a CX5530, which I believe is SB16 compatible. Anyway, I 
can't get sound to work on it. The drivers seem to all be in place, as 
Knoppix has really good hardware detection. Here is lsmod's listing:

cloop                   8068   2

and here is the relevant stuff from dmesg:

Cyrix Kahlua VSA1 XpressAudio support (c) Copyright 2003 Red Hat Inc
kahlua: XpressAudio at 0x220
kahlua: XpressAudio on IRQ 5, DMA 1, 5

If I 'cat some_audio.au > /dev/audio' I don't get any errors, I just don't 
get any sound.
By the way, I'm doing all this from init level 2. I've checked the obvious 
stuff like the speakers and cables too. I'm not finding much info on the 
Knoppix web site or via google. Maybe my hardware is just hosed.
