Public bug reported:
On Ubuntu 19.04 on my Thinkpad T470s, my Sony WH-1000XM3 headphones pair
using Bluetooth with no problems, and use A2DP by default. If I then
power off the headphones and power them back on, they reconnect but use
HSP/HFP and sound terrible. If I manually go into the sound settings,
A2DP is offered as an option, but selecting it doesn't take effect. The
headphones remain stuck in HSP/HFP mode.
Unpairing the headphones and re-pairing them again selects A2DP by
default, until the next time I switch the headphones off. Then they're
back to stuck in HSP/HFP until I unpair them once again. I therefore
need to unpair and re-pair them every time I want to use them, which is
a nuisance.
I'm not sure which package is responsible for handling this, so am
reporting to for bluez since it provides /etc/bluetooth/main.conf. If
I'm wrong, please re-assign.
