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):

After pressing play/pause button on the headphones or manually reconnecting,
a2dp_sink is available:

Title:
Bluetooth headphones only use A2DP when connected manually
Status in alsa-driver package in Ubuntu:
Confirmed
Bug description:
Issue with Sony MDR-1ABT Bluetooth headphones:
Once paired, the headphones will be connected automatically whenever they are
switched on. However when connected this way, only the HSP/HFP profile will
work and trying to change to A2DP in sound settings does nothing.
If the headphones are then manually disconnected and reconnected from
Bluetooth settings, they will initially use HSP/HFP but then selecting A2DP in
sound settings will successfully make them use A2DP.
