Fedora Users — Crystal Audio

I've got fedora installed and working well on an IBM Thinkpad 600E. There are really only two problem I've run into. One has to do with my Cardbus Nic, which I still think I can figure out, the other has to do with the sound system on this machine. The only way I can get any sound out of it is to play an audio CD. Playing a CD works fine, but nothing else works at all. In fact, if I put the mouse cursor on the little sound icon on the bar it gives me a message saying "No Audio Device". On bootup there is a "no sound server" error that comes up so I have to assume that either this hardware is just not supported, or there is something wrong with it. This machine was running Win98SE until a couple days ago and the sound system worked fine. I have to assume that this is an OS/Driver problem, but I can't figure out which. Any ideas out there?
