I have the same MoBo and the Driver Disk I have , has a Revision Number:225.06 The MoBo also has a couple of Revision Numbers. Which should be printed on the Side of the box it came in, try identify these then email ASUS with the Revision Numbers of your MoBo & Driver Disk , you may have the wrong disk for your MoBo. All else fails, update your Bios one stage at a time , each time trying to install your Audio Driver after the update. Regards...
