I just installed Linux Redhat 9

I have an Abit IC7-G Motherboard
Intel P4 3.06 Ghz Processor
Realtek AC'97 Audio card (built in)

When I test for the sound card it says there is no sound card found. Under hardware when I click on the soundcard option it says camera. Which I'm guessing is my logitec quickcam. I have the driver but its only for windows. I can't find a linux driver. I've also be told the device files might be on my computer. If so help me find them. If you can help be I believe I'm having the same problem with my network card.
