How to get Reverb headset to work

It all worked before SU12. It used to be that if I was not in VR then sound came through my PC speakers. Once I enabled VR sound no longer came through my PC speakers sound came through my Reverb headset.
Headset still works but not sound (in MSFS) in my headset.

Is the headset not working at all?
Video works fine just the audio does not play through the headset. Works fine in other apps.

Is VR not showing up in MSFS and therefore you are unable to activate VR?
I don’t recall saying that the headset did not work … just sound in the headset.

Are you using MSFS store or Steam version?
MSFS Store

Using OpenXR or Steam VR?

Windows and drivers etc. up to date?
