Title:
Bluetooth, when turned off, does not disconnect from connected
headphones
Status in alsa-driver package in Ubuntu:
Confirmed
Bug description:
It seems like there is some sort of "disconnect" message that other
operating systems (Android, MacOS) send to all connected bluetooth
devices when the computer/phone's bluetooth system is turned off,
which Ubuntu 20.04.02LTS does not.
When I connect my headphones (Aftershokz Aeropex) to my 20.04.02LTS
Ubuntu system (running on a Thinkpad X1 Carbon 3rd Gen), and then turn
off bluetooth entire from Ubuntu settings, the headphones act as if
the connection to its source device (i.e., the computer) has been lost
unexpectedly, exactly in the same way they would if I'd walked out of
range: they give a periodic "out of range" beep until I power-cycle
them.
If I specifically go into Ubuntu bluetooth settings and disconnect
just the headphones, then the headphones do a quick beep to
acknowledge the disconnection, and do not give "out of range"
notifications.
The expected behavior, which my two main other source devices do (a
Macbook, my Android phone), is that when one turns off the bluetooth
system, the source device sends that "disconnect" message to the
headphones (headphones beep once), and there is no "out of range"
beeping afterward.
