Use pulse audio volume control. See if it would help. Mine also broke after some system update. With this I was able to select bluetooth profile as well as set audio out via bluetooth. Before finding this bluetooth headset wouldnt work correctly on elementary os, but never needed it in linuxmint.

apt install pavucontrol

you're missing his point. the issue is not the specific issue but the endless litany of issues.

Didn't miss the point at all. Why would you assume that? I faced a similar problem as parent and know the pain point. Was just trying to let parent know of a solution I found useful.
