I found it in latest snapshot 20w18a and I'm not sure if this was before this version. When I press F5 to see my face, while I was listening a music disk, I hear, that side changed. If I am not in F5 it's from right, but when I press F5 it's coming from left. I think, this is not how it should be. Maybe, it's because music connected to camera and not to the player.

(Sorry for bad English. I tried my best to write it all right. I hope you understand me...)
