I just got a new laptop (Lenovo ThinkBook 14s Yoga) and installed Ubuntu 21.04. My Bluetooth headphones connect and work fine for a few minutes, but then they disconnect and reconnect in HSP/HFP mode. I don't need to use the microphone so I want them to be in A2DP all the time, and the disconnects are getting very annoying.
I've tried disabling this mode a few different ways:
- in
/etc/bluetooth/audio.conf, I added
[General]
Disable=Headset
- in the same file I've also tried
[General]
Disable=Source
[Headset]
MaxConnected=0
I also tried adding
Disable=Headsetto both the[General]and[Policy]sections in/etc/bluetooth/main.conf. This just caused warnings in the syslog.
I've tried this setting in
/etc/pulse/default.pa:
.ifexists module-bluetooth-policy.so
load-module module-bluetooth-policy auto_switch=false
.endif
The bluetoothd entries in syslog look like they're just coming from starting and stopping the service after changing the config files.

None of this has worked so far and I'm not finding any other ideas in my search. Any other suggestions?
