Sound card stops working after hibernate or standby

Okay, first the background...so, a few weeks ago after a nasty, nasty virus, I deleted my hard drive and re-installed my system from scratch. I'm running Windows XP on a Dell E510. I could not find the disks with all the original Dell Drivers, but after a lot of painful trial and error, I finally got pretty much everything working on the computer again. Everything except sound.

I've got a Creative SB Audigy 2Z soundcard. When Windows loads after re-start it detects my sound card, but also an additional sound device with the yellow warning label in the Device Manager. When I uninstall this "unknown device" and then uninstall "Microsoft UAA bus driver for HD audio" under system devices, then I get my sound back. I'd be reasonably happy just doing that, but after every hibernation or even standby, I lose sound. I check device manager, but these conflicts are no longer visible. The only way to then get sound back is to re-start the system and repeat the uninstallations described above. I've opened up the case and am not aware of any other card in a PCI slot, and certainly not anything with sound.

Any advice/suggestions greatly appreciated!

You may have an outdated or incompatible device driver which may not support power management. Heres some more information

This seems to be the most up to date driver:

Thanks for the suggestion. I had already installed the most recent driver for my sound card, so that's not the problem.
