Title:
Bluetooth headphones won't use A2DP on reconnect
Status in bluez package in Ubuntu:
Confirmed
Bug description:
*** This bug is the same as bug 1724919, but is NOT A DUPLICATE
because that bug was closed because it was reported for Ubuntu 17.10,
which is out of support. This bug is for newer versions, such as
19.10. PLEASE DO NOT MARK THIS BUG AS A DUPLICATE. ***
On Ubuntu 19.10 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.
