Title:
Bluetooth A2DP audio device disconnect automatically after long time
using (almost 49mins)
Status in pulseaudio package in Ubuntu:
Incomplete
Bug description:
After upgrading Ubuuntu 18.04 LTS to 20.04 , when I watching
Netflix(by Firefox) videos with my bluetooth speaker (Lasonic
i931BT), I found that almost every 49mins ,the video suddenly slow
down and then sound stop transmitting to my speaker. It shouldn't
happen.
I check the pulseaudio mixer's output device. My speaker dissappeared.
Only "Dummy Output " showed. (As the screenshot ) Everytime, I need go
to bluetooth manager to disconnect the speaker, and wait it
automatically connects again. Sometimes it works, but sometimes does
not. I need to reboot to fix it (Power off the speak won't help ).
