Regardless of whether bluez or pulseaudio are at fault, this feels like a recent regression since it's now affecting my Bluetooth speaker hardware which has been unchanged for several years. And it looks like 18.04 and later received updates to both packages this year.
I guess the most useful thing to do would be to try a fresh 18.04 installation with the oldest packages, verify the bug does not exist and then figure out which update introduced the bug. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1845046 Title: Bluetooth headphones/speaker default to low quality headset mode and fails to switch to A2DP when selected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1845046/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
