Windows 7: Intel HD 2000 Not Outputting HD Audio

Hello,

I am looking for help to get the HD 2000 graphics on my PC to output the HD audio formats in Bitstream format to my AV Receiver.

Specs;
CPU; Intel i3 2120
OS; Windows 7 64Bit Ultimate, Genuine copy.
Motherboard; ASRock B75M
RAM; G Skill 2x 2GB DDR3

AV Receiver; Onkyo TX-NR579
Software; Arcsoft TotalMedia Theatre 5

I have installed and updated all the drivers that came with the Motherboard. I have run the Intel Driver Update Utility and I'm running the latest drivers.
I have set TotalMedia Theatre to output the audio as a Bistream format.

The Intel Display Adio has been configured to output the HD audio formats:


However, most time the PC boots it converts back to this; (Not supporting the HD audio formats). It takes several re-boots to go back to the above and supporting the HD audio formats.





Even when the Intel Audio says it is outputting the HD audio it will only output the DTS not DT HD-MA when I play a BluRay movie.

What should I do?
