Option to force 7.1 sound

Hi,

I would like to see an option to force sound output to 7.1 so I could use Windows Sonic while using my headphones.

Right now games detects sound card configuration in Windows and forces output according to it, so even though I turn on Windows Sonic with 7.1 option checked for my sound card, sound card itself is still configured to stereo and game will output only stereo sound, because of that.

Obviously I would like to see proper headphones support like Dolby Atmos for Headphones or DTS Headphone x v2.0, but I figure that this simple option to select output configuration would be much more simple and faster to add.

Currently my main issue with stereo config for headphones is not being to tell certain directions of incoming sound. I can tell if sound comes from left or right but if the sound comes from front or behind it still sounds exactly the same, which is something that Windows Sonic would help me with. Yes, there is another issue with sounds from below of above, but again it is something which would be more difficult to implement.

Also, big part if not majority of playerbase is using headphones, so I think that better support for headphones would have a big impact and might help to solve some of sound issues which are mentioned here and reddit.
