Public bug reported:
I learn from
https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/508522 that in
recent Ubuntu releases the behaviour of Bluetooth headset profile
handling changed, so that it's set to A2DP profile by default and
automatically switched to HSP/HFP when a phone app needs to use the
headset.
In Ubuntu 16.04 I could set the HSP/HFP profile on my Bluetooth haedset
and this was remembered across disconnections and reconnections of the
device.
In Kubuntu 20.04 my headset is set to A2DP profile whenever I
(re)connect it, even if I previously set it to HSP/HFP profile.
This is really annoying because Linphone does not cause any switch and
will simply work with an output-only device when the headset is
currently connected in A2DP profile mode on start. The Mic of course
won't work (Linphone will automatically choose another Mic device).
If I understand it correctly, the problem lies in Linphone that does not
set the proper media.role, however is there meanwhile a workaround to
restore the previous behaviour?
I tried to change /etc/pulse/default.pa adding auto_switch=false
parameter to module-bluetooth-policy, so that the corresponding line is
changed to:
load-module module-bluetooth-policy auto_switch=false
however this does not solve the problem that my headset is always reset
to A2DP profile on reconnection and the HSP/HFP profile setting is not
remembered.
