Rolled back to 3.8, low and behold, sound works. Not sure why this happens for me and not everyone, but I can't even check out the 3.9 beta...no sound! Oculus Home devices tab shows no audio, and nothing works to fix it. I unplugged /plugged back in the audio cable, I reset Oculus Home, I ran Windows sound trouble shooter, nothing worked except rolling back to 3.8.
/disappointed
I hope this gets seen by who ever it needs to be seen by. I hope 3.9 doesnt go live with this bullshit.
But it turned out to be a Windows update that fixed it. However, now Oculus says I should update my USB driver ( which is nonsense as it's the newest), and it works fine so I ignore it.
Aaaaaaaaaaaand no sound in Rift S again. Thought it was lack of a windows update, cuz it fixed its self after I updated to a cumulative update, now the issue is back.
