I just rebuilt my XBMC MediaPC with Windows 7 so that I could get the DXVA hardware acceleration (down to a peak of 20% CPU utilisation on 1080P intensive scenes, awesome!).
Anyway, I had some real struggles on the way and thought this post might stop some other people from having to stay awake until the small hours with the same problems.

Anyway, I had some real struggles on the way and thought this post might stop some other people from having to stay awake until the small hours with the same problems.
Surround/DTS/AC3 Audio over HDMI with AMD/ATi Chipset
- Install the AMD Catalyst Graphics driver suite first
- Install the RealTek Audio Drivers (not the basic HDMI Audio Driver but the full suite)
- Right click the Audio/Speaker icon on the task bar and choose "Playback Devices"
- In the list of devices choose "Realtek HDMI Output" and click the "Properties" button
- Click the "Custom" tab and tick the box that says "Allow AC3/DTS/WMA Output"
- Reboot your Windows 7 XBMC PC
- You should now have multi channel sound in XBMC over HDMI
Stuttering/Jerky/No Sound After Resuming From Pause
- In XBMC go to "Settings"
- Go to "System (Cache & Hardware)"
- Go to "Audio Output"
- In "Audio Output Device" choose the DirectSound Driver and not Wasapi (for ATi/AMD this is "DirectSound: RealTek HDMI Output (ATi HDMI Audio)")
Improve Playback & Interface Performance
- Click "Start" and then "Control Panel"
- Click "System and Security"
- Click "System"
- Click "Advanced system settings" in the left hand menu
- Click the "Settings" button in the "Performance" section
- Choose "Adjust for best performance" and click "OK" and then "OK" again
