Public bug reported:
I am having a problem connecting a bluetooth headset as HSP/HFP
(headset_head_unit). It seems that the only way to use my headset as an
HSP/HFP device is to set module-bluetooth-policy auto_switch=2, as A2DP
is the hard-coded default. It's hard to find information because of the
overwhelming number of issues people have had getting HSP/HFP to work in
the first place. auto_switch=2 does switch the protocol to HSP/HFP, but
in such a way that Discord does not recognize that the device is
connected any longer. If I manually switch my headset to HSP/HFP before
joining a voicechat channel, everything works as expected, but I can
find no way to default my headset to HSP/HFP.
Steps to reproduce:
Open Discord, having previously set input/output to Bluetooth device
Connect Bluetooth headset
Join Voice Chat
Expected result:
Bluetooth unit sets profile to HSP/HFP
Discord outputs and inputs via the headset
Actual result:
Bluetooth unit sets profile to "off"
No output or input through Discord
