Log:

Audio Framework: handle more configuration scenarios. Bug fixes

Bug fixes:
- If re-encoding to AC3 was occurring while downmixing: audio would be distorted
- Couldn't play 6.1 or 7.0 audio with LPCM/Analog out
- Wouldn't play DTS-HD High-Res unless HBRPassthrough was unchecked

New Features:
* We should now be able to play any number of channels combination from 1 to 8.
  - 1,3,4 will be downmixed to stereo
  - 2 and 5 will be upmixed to 5.1
  - 7,8 will be downmixed to 5.1 if supported, or stereo otherwise.
  This will only occur if the requested audio configuration isn't supported.
* Mono upmixing can be toggled between stereo or 5.1
