After apt packages upgrading to the latest version, today I tested 7 hours (continuous Netflix video watching ). It didn't happen again. I guess the bug is fixed by someone.
I still leave files here. I guess It may help for researching. ** Attachment added: "a2dp_situation_report.tar.gz" https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1867944/+attachment/5341378/+files/a2dp_situation_report.tar.gz -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1867944 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 ).
