Sorry, I should have noticed this earlier. A2DP does not support microphones. If you want to use a microphone then yes it will switch to low quality HSP mode. This is not a bug, but is a limitation in the Bluetooth spec. Everything is behaving correctly... But something better is on the way, so I will mark this as a duplicate of bug 1838151. ** This bug has been marked a duplicate of bug 1838151 Poor quality audio with modern Bluetooth headsets in HSP/HFP.

Switch to use the microphone of the headset and will switch to low-quality audio HSP Happens with the upgrade: bluez:amd64 (5.50-0ubuntu4 -> 5.50-0ubuntu5). Before that upgrade, everything was working fine. Only the automatic selection of A2DP fails sometimes but the microphone and A2DP were possible to use. After the mentioned upgrade to 5.50-0ubuntu5, it's just impossible to use the microphone and the A2DP audio at the same time. When I do the switch in the input device in the syslog it's the following message: kernel: Bluetooth: hci0: SCO packet for unknown connection handle 0 I tried to downgrade to 5.50-0ubuntu4 but didn't work, the A2DP is not usable at all. pulseaudio[8370]: Refused to switch profile to a2dp_sink: Not connected Description: Ubuntu 19.10 Release: 19.10 Device: LE_WH-H900N (h.ear) Regards, To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1868286/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
