I recently bought a new gaming rig, and I've been trying to get the audio to work.

The motherboard is a K8N-SLI-F, with Realtec AC'97 ACL850 integrated card.
I've tried all the possible device drivers from the manufacturers website, as well as the ones from the motherboards website.

Is there any reason why my sound still isn't working?

EDIT: Forgot to add, my OS is Windows XP Professional SP3.
