Well I just completed a downgrade from Vista to XP Pro and everything is working fine except for the audio. I have a Compaq C504 US notebook and have downloaded all of the associated drivers but I am still getting a yellow exclamation mark for Microsoft UAA Bus Driver for High Definition Audio under Device Manager. I have tried to update the driver by loading hdaudbus.sys but I get an error message that says Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39). Any help would be greatly appreciated. Thanks.

SuperSam,

Yea I tried that one but I get a error message that says driver installation failed, could not find the device for this driver. I'm thinking I may be missing something in the system chipset that "turns on" the onboard audio device hardware. Any other ideas? Thanks.
