Why my bluetooth is choppy and why removing some services fix it?

My bluetooth speakers and headphones are often choppy. I find solutions on the web.

Some suggest to go to devices and then tu off some services.

I got to remove services such as audio sink.

Which kind of strange. I am, after all, using that bluetooth speaker as well, a speaker. So that sounds like it means I am using it for audiosink.

Surprisingly enough, tuing that audio sink service off does fix the choppy sound.

My cellphone can coect to my devices just fine without any problems. My PC need some "hacking"

Why?
