Post 7 and 8 of this thread is not visible for some reason. In any case, the driver file you link appears to be just the AMD adrenaline software, not a library of drivers. I did follow the instructions you gave. however, when I removed a device from the Device Manager, Windows seemed to automatically re-install it. When I tried to update the driver and opt to look in the unzipped version of the directory you linked, Windows just said the best driver was already loaded. Am I supposed to install the Adrenaline software? I had already tried that but it did not solve the issue. It could be that I didn’t do it correctly.
One thing that is odd is that there is an Other Devices section with one device, ‘Audio Controller’ that doesn’t have a driver and Windows cant find one.
