> Using several different bluetooth headsets I find that the Bluetooth functionality of the built-in AX200 module of my motherboard keeps randomly disconnecting. I found that this has been fixed in recent Linux firmware updates, but I am not sure that fix has landed yet in Ubuntu Hirsute.

Perhaps someone can comment on whether this has been merged in. I am still experiencing disconnects with 1.197.1 at least.
