AB9 QuadGT Win764 No Sound

[reckless67]

I have just recently installed Win764 on my AB9 QuadGT and it installed all drivers except for one unknown device. Under Sound, Video and Game Controllers I have, 1. ATI High Definition Audio Device, and 2. High Definition Audio Device. I can't get any sound out of the analogue audio out jack on the back of the motherboard. I'm assuming that the unknown device is the AC97 Audio, but I can't get and drivers to install, keep getting an error "Install Realtek HD Audio Driver Failure !! [Error Code : -0001]". I have downloaded the "r1.90" HD Audio drivers from Abit's website, and it won't even install. I have also downloaded the "6305_Vista_Win7_PG537" from Realtek's website and it won't install either, just keep getting the "Windows can't verify the publisher of this driver software", and if I select "Install this driver software anyway" it just keeps looping back to it.
I hope someone can help with this.

Thanks

I figured it out, I downloaded the 2.52 HD Audio drivers from Realtek's site and they installed fine and now I have audio.
