I'm sure this has been asked to death but it seems a lot of the information I find, while partially relevant, is never really as to-the-point as I'm after.
I have my PC send audio from my GTX 770 over HDMI to my 5.1ch Onkyo AVR. This handles the audio and sends the video out to my display. Windows is configured to treat my setup as 5.1ch and correctly sends multichannel PCM audio to the AVR.
For sources that have 5.1 channels this is great. Games play as expected with full surround support, as do movie and tv show backups.
The issue (if you can call it that) is when I play stereo sources, such as older movie and tv backups, or music (via my Xbox Music Pass subscription). What happens is that the two channel stereo is sent to the AVR as 5.1 multichannel, with the remaining surround channels having no source to play. As the AVR is receiving what it sees as multichannel (and not stereo) I am unable to use its upmixing features (such as DD ProLogic 2).
Is there a simple (ideally OS-level) way to have the audio send only 2 channel stereo if the source file I am playing on the machine only supports such, while maintaining support for 5.1 multichannel if the source supports it?
I've noticed a lot of similar threads end up suggesting bitstreaming. I'm not entirely familiar with this practice, but am lead to believe it would allow me to send stereo signals to the AVR without having to change the Windows configuration from 5.1, allowing the AVR to recognise a stereo source and act accordingly (using its upmixing algorithms to create surround channels for the stereo content). I may however be mistaken and clarification on the matter would be greatly appreciated.
I've checked the nVidia control panel for settings related to audio over the HDMI port however its awfully bare- simply providing an on/off switch per connection.
Any help here would be greatly appreciated.
