Description Richard Monk 2021-03-12 18:32:56 UTC
Description of problem:

When using A2DP headphones, sometimes they will disconnect and reconnect after 10-20 minutes into HSP mode, and A2DP is unavailable.  After a bug report, this was discovered to be caused by accidentally removing remote SEPs.

Bug: https://github.com/bluez/bluez/issues/102
Patch to fix: https://github.com/tedd-an/bluez/commit/fac790455a8a2d1fd7973db1fed2f297d67f5d9f

Version-Release number of selected component (if applicable):

Steps to Reproduce:
1. Connect bluetooth headphones to your system
2. Play audio for some time

Actual results:
Audio will suddenly cut out with no warning, and the headphones will disconnect or reconnect in HSP mode. 

Expected results:
Audio keeps playing

Additional info:
Upstream has a patch to fix this, I patched bluez-5.56-1 on Fedora 33 x86_64 and the issue has not returned, so I think this is a good fix.
