** Description changed: 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. + 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. + --- + ProblemType: Bug + ApportVersion: 2.20.9-0ubuntu7.21 + Architecture: amd64 + CurrentDesktop: ubuntu:GNOME + DistributionChannelDescriptor: + # This is the distribution channel descriptor for the OEM CDs + # For more information see http://wiki.ubuntu.com/DistributionChannelDescriptor + canonical-oem-somerville-bionic-amd64-20180608-47+beaver-three-eyed-raven+X92 + DistroRelease: Ubuntu 18.04 + InstallationDate: Installed on 2019-11-22 (415 days ago) + InstallationMedia: Ubuntu 18.04 "Bionic" - Build amd64 LIVE Binary 20180608-09:38 + InterestingModules: rfcomm bnep btusb bluetooth + MachineType: Dell Inc.
