Public bug reported:
Hi,
When having a bluetooth headphone (JBL Live) connected using the A2DP
pulseaudio sink, the output sound suddenly stops during a music
streaming of videocall session. Sometimes just disconnecting and
reconnecting the headphone works, but some times reconnection is not
possible anymore due to the hanging of bluetoothd. Bluetoothd still
appears in the processes list, but cannot be killed, neither with "sudo
service bluetooth stop" or "kill -9":
$ ps afx | grep blue
9597 tty2 Sl+ 0:01 | \_ gnome-control-center bluetooth
5405 ? Ss 0:00 \_ /usr/lib/bluetooth/obexd
10694 pts/0 S+ 0:00 \_ grep blue
20548 ? Ds 0:03 /usr/lib/bluetooth/bluetoothd
All programs keep working normally, only bluetooth is affected as well
as the bluetooth settings page.
The only solution is a hard reboot. A soft reboot doesn't even work: the
systems keeps trying to end the bluetoothd process so one needs to press
the power button for a few seconds to terminate the process.
$ bluetoothd --version
5.48
$ uname -a
Linux omer 5.4.0-58-generic #64~18.04.1-Ubuntu SMP Wed Dec 9 17:11:11 UTC 2020
x86_64 x86_64 x86_64 GNU/Linux
Using Ubuntu 18.04.5 LTS preinstalled on a Dell XPS13, which has been
working nice for over one year now just like previous versions.
