I installed Slackware v9.0 on a machine that already had an ISA sound card installed and when I go into KDE v3.1 it picks up that there is a sound card present, but that it isn't installed properly and it doesn't know what it is. I checked out the sound card and it is an ISA, and the chip on the card has printed on it ...

Crystal

It looks like it possibly is an AOpen brand, because there is an "A" printed on the card also that just looks to me like the "A" in the AOpen logo but since it doesn't say "Open" after it, I can't be for sure on this yet. Otherwise printed on the card is also ...

AW35/AW37

P/N: 90.18610.010

I'm sure this card isn't that great of a sound card, but I thought it would be fine for use with this Slackware box which I primarily will be using for internet tasks, some image manipulation and a couple other random tasks. I did a quick search on Google and some others for some linux drivers for this model sound card and haven't come across any yet and thought these forums would be the best place to really ask. Thanks for the help.

If it's an AOpen, it isn't supported, but I think that is a Crystal chipset.

You might be able to install sndconfig and get it to work.
