I recently purchased some server-grade components to replace a broken motherboard, and I was planning on using the server as a dual-purpose HTPC and Hyper-V server, so I installed Windows Server 2012 R2. Unfortunately, I have not been able to get the AMD High Definition Audio Device driver to work with my XFX Radeon R7 240 R7-240A-CLF2 video card. The device just shows up as "Unknown device" in Device manager and it refuses to install the HDMI audio driver even if I point directly at it. If I try to auto-detect the driver on the Unknown device, it detects it as a "High Definition Audio Device" and gives an installation error and says the driver installation file for this device is missing a necessary entry.
Furthermore, Catalyst Control Center refuses to run on the machine. The ACEEventLog includes the following error whenever I attempt to start the program.
The driver installed fine when I tried it on Windows 8.1. Any ideas of how to get this to work?
