I have the same problem with Sony WF-1000XM3 and Ubuntu 16.04. I realized that when the headphones connect automatically, they don't appear when running ``pacmd list-sinks``. If I disconnect and reconnect them manually, they do and a2dp is used.
I wrote a couple of scripts to automatize this and temporarily circumvent the issue. ** Attachment added: "checkBTConnection.zip" https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1845046/+attachment/5311468/+files/checkBTConnection.zip -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to bluez 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 Status in bluez package in Ubuntu: Confirmed Status in gnome-control-center package in Ubuntu: Confirmed Status in pulseaudio package in Ubuntu: Confirmed Bug description: Whenever I turn on my headphones theyll connect to my computer but im able to hear the input audio from my microphone and low quality output audio.
