I also experience this issue with 2 different Brand of Bluetooth Headset: ATH-CRK75BTH Edifier W200BT
Problem also appears every time I switch bluetooh devices as INPUT device and OUTPUT using HEADSET Unit (HSP/HFP). Input indicator bar doesn't move and test OUTPUT doesn't produce any sound. When I tried video conferencing with my friend, he couldn't hear my voice and of course I can't hear him either. This is fresh installation using Ubuntu 20.04 (no prior Ubuntu or other Linux distro in this laptop). A2DP mode works normal. Currently I'm using internal laptop microphone and A2DP combination for video conferencing. Just now, I ran "sudo apt dist-upgrade, some packages were updated. But still not work for HSP/HFP mode output and Bluetooth mic input. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1878194 Title: [Sennheiser HD 4.50 BTNC] Bluetooth headset not working when selecting HSP/HFP audio profile in Focal Fossa To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1878194/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
