Sound on Knoppix 3.3

[toddvan]

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. Here is lsmod's listing:

apm 9768 1
rtc 6940 0 (autoclean)

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. Maybe my hardware is just hosed.

Hi toddvan,

I may not be able to help too much but would suggest
you check the following until real help comes:

When you tell us your version of KNOPPIX alway
give the release date. KNOPPIX is very much experimental
and new releases may come out in a few days or weeks.

V3.3-2003-11-03 had a problem with alsa sound.
A newer or older release date may work.

A frequent sound problem is solved by understanding
that just because you don't hear anything, don't mean
sound is broken --
KNOPPIX likes to pull of little trick of starting with volume 0.
From a shell type aumix and be sure the sound is loud
enough to hear.

Best Wishes
