I built a new PC a couple of months ago and it works pretty well. The only problem I have is that my sound will sometimes just stop working out of nowhere until I restart. I will be listening to music or playing a youtube video, for example, and when I press pause and resume, switch to a different song, play a video in another tab etc., the sound will suddenly disappear for the entire system and stay gone for good. This only affects the speakers connected via SPDIF - my monitor speakers continue to work. I don't have another way to connect the speakers, unforunately.

My setup:
Win11
AMD 7800X3D
ASRock B650 Steel Legend Wifi
Edifier S330D speakers

Another thing that may be connected:
The speakers came with a knob that's connected to the subwoofer. It controls the volume of the speakers and lets me turn them off. When I turn them off, my screen turns off and on again.

Grateful for any suggestions. Not sure wtf is happening.
