I got a Oculus Rift S a couple of days ago. It worked prefecly for me and I played a couple of hours Half life: Alyx. Out of sudden
the sound became crackling (like scratches/ dust on old audio records) in the middle of a game sequence. I finished the game and
checked possible root causes for this issue. I didn't changed anything witin my setup.
I fear that it is an connection issue within the internal audio speakers and not an driver/ software issue!
