I guess you used the modified packages when you paired with this headphone the 1st time, and it only supported HSP/HFP Transport at that time. And this configuration is remembered.
After you use the correct packages, it will not change since the configuration is already remembered/saved. You could run bluetoothctl devices and connect, this will make a new connection, and it has both A2DP and HSP/HFP Transports, but these two commands will not replace the saved/remembered configuration, so after disconnect and reconnect, it has only HSP/HFP Transport, you need to run bluetoothctl again. Maybe you could remove and pair the headphone to let configuration have A2DP, then you don't need to run bluetoothctl time and time. I tested on stock ubuntu, it is gnome desktop. If I paired the device with gnome-control-center bluetooth applet, it will save the configuration, and if I ran bluetoothctl devices and connect, it will not save the configuration. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1891648 Title: [0cf3:e301 Qualcomm Atheros]Cannot switch to A2DP profile w/o restarting bluetooth.service [pulseaudio: Refused to switch profile to a2dp_sink: Not connected] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1891648/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
