Problem with Audio drivers

Hi,
I have this mainboard : Asus P5GDC Pro with integrated sound card. Automatic installation of High Definition Audio Device fails and it fails each time I try to unninstall the driver and let windows install it again. I tryed some UAA drivers from Vista, but after installing it behaves like I have not installed anything.

On Win XP I was running C-Media High Definition Audio driver and it worked without any problems. Now it shows "This device cannot start. (Code 10)"

Also in system tools my High Definition Audio controller shows (This device cannot find enough free resources that it can use. (Code 12) If you want to use this device, you will need to disable one of the other devices on this system. You need to restart your computer before the changes you made to this device will take effect) , but its displayed twice there and the other one works fine.

Windows update is also not solving this problem...

any ideas what I should try? Please.. I really need sound.
