When i press ctl tab to enter VR the sound comes out of my main speakers & does not switch to my index headphones.
This is despite selecting index in sound options. Radio does come through my headphones though. Windows is showing index in the sound option correctly but the game seems to just override this.
Every time i start the game in 2d it switches back to default windows sound source.
The only way i can get it to work is to start FS with VR already on in steam but then there is a dramatic drop in performance. That is perhaps a different issue/bug because i do not see why it should turn the game into a slideshow but it does.
As mentioned in the original post windows is already showing the correct (index) sound source. Audio from steam vr menu also works correctly.
Its probably something to do with the fact that the index audio only becomes availably when steam vr is on. In every other software & game it just switches the audio to vr as soon as vr is switch on but FS just ignores it unless VR is already on when i start the game.
