Thinkpad audio becomes 'crunchy' until cycling audio

So I have a problem on a Thinkpad T16 Gen3, where after a while of audio playing fine, it will seemingly randomly become ‘crunchy’ and awful. It persists until I swap the audio config to ‘pro audio’ and then back, which fixes it for a while, then it will eventually break again.

I took a cellphone video of it since I don’t have/know of a screen recorder with audio. Besides, I figured it might not pick it up and then I’d have to wait for it to break again.
