There are some problems with sound engine of minecraft JE 1.16.5.

I use a bluetooth earphones (Airpods) to play minecraft, but there are three phenomena:

1.When I link my earphones after start minecraft, it will not play sound in earphones (It play sound on the speaker.

2.Then I try to disable speaker. But the game crash and the final line of log is an exception from the sound engine.

3.Sometimes when I disconnect my earphones (such as I go for lunch), the game crash and a exception from sound engine.

I think you can solve it by adding an option for choosing speakers.
