I am running Ubuntu 18.04 and have Sony WH-1000XM2 bluetooth headphones. Bluetooth connection is established automatically but in order to get any sound out of the headphones I need to:
1. Manually disconnect and reconnect the headphones from bluetooth settings or 2. Press play/pause button on my headphones (after this a2dp_sink is available) and go to sound settings to select headphones as output device. After the bluetooth connection is automatically established I see the following error message in system log: pulseaudio[3124]: [pulseaudio] module-bluez5-device.c: Profile a2dp_sink has no transport The command "pacmd list-cards" displays the a2dp_sink as unavailable (full device output attached): ... profiles: headset_head_unit: Headset Head Unit (HSP/HFP) (priority 30, available: unknown) a2dp_sink: High Fidelity Playback (A2DP Sink) (priority 40, available: no) ...
