The following did the job for me. Remember to change the headset to AD2P under SOUNDS in Ubuntu on your headset.
--- Ref. from source: https://askubuntu.com/questions/1139404/sony-noise-cancelling- headphones-wh-1000xm2-3-and-bluetooth-initial-autoconnec --- The "ambient noise" you're hearing is a loopback from your computer's mic coming out through your headphones. This is apparently due to a bug with A2DP's implementation. I fixed this in Ubuntu 19.04 by installing Blueman and pairing my headphones as an Audio Sink rather than a headset: Unpair your headphones, if they're currently paired. sudo apt install blueman Open Blueman, click on "search". Select your headphones, right click, select "Setup" Make sure they're paired as an Audio Sink rather than a Headset Select your headphones as an audio output in your sound settings If you have Spotify open throughout the process you have to restart it. -- 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 such as Sony WH-1000XM3 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/pulseaudio/+bug/1845046/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
