Public bug reported:
using ubuntu-bug
I have bluetooth speakers QM20HD, and once connected these are recognised and
available in sound/output device. This works normally.
However after say 40 minutes, audio regularly drops out. Output device no
longer lists QM20HD. Even if one reconnects speakers sound/output device no
longer lists QM20HD as option.
I am currently rebooting to continue to use speakers.
up to date 26.04 recent vanilla upgrade on 2015 macbook pro. Firefox 150.0.2
laptop is kept about 1 metre from speakers.
