Mine does the same thing, but I don’t know what causes it. I’ve only experienced it twice in the time I’ve had it but both times I was streaming from Netflix or Plex, I don’t remember which.

My wife has had it a few more times, usually while watching Peacock or so like that.

Restarting always fixes it. I can’t help but to think it’s a software bug, as if it was hardware related it would happen randomly and restarting would be less likely to fix it.
