I had something similiar where I had noticed no matter which driver I installed it would always show "High Definition Audio Controller" with an exclamation mark and it was driving me crazy as couldn't get HDMI to be recognised for audio - only video (ie extend or mirror displays worked fine).
I have now worked out it's def a driver conflict between what appears to be Microsoft's standard driver for audio (that comes with Windows 8 via online driver collection) and realtek or amd drivers (when you try to install either of them).
I finally had a eureka moment this weekend and started a new install of Windows 8.1 BUT this is what I did:
1. I disabled the onboard sound via the BIOS
2. I went through the windows setup but on setup I chose customize settings rather than express settings - in here you need to ensure (for now) that it won't try and find/download and install drivers via windows update so turn this off for now
3. Now when I finished the rest of the setup and got into Windows I simply downloaded the realtek AMD driver from: http://www.realtek.com.tw/downloads/down...Down=false
Select "ATI HDMI Audio Device" (2.70) and run and install this.
4. Restart your PC and you will have the HDMI audio working now. I tested this with the AMD Catalyst Drivers too and it did work ok too but I'd read in a few places it was better to use the Realtek driver as it was better(?).
I have tested and DTS and Dolby Digital definitely work fine (all my amp can support - it's old!).
Anyways it is all working fine and I know if I ever need to rebuild or anything that I can confidently get it working fine.
