<pre>Bluetooth headphones were working since long ago. A few days ago I wanted to
have a voice call so I tried to switch audio profile from 'High Fidelity
Playback (A2DP sink)' to 'Headset Head Unit (HSF/HSP)', PulseAudio crashed and
since then I can no longer get Bluetooth headphones to work.
Debugging stuff:
-----------------
- Bluetooth headphones pair fine and all, but the sink is not shown in the
'Output Devices' tab in pavucontrol, and the 'Configuration' tab shows the
device as 'Profile: Off'
- If I attempt to change profile via pavucontrol or via blueman, PulseAudio
stalls for a minute and then dumps core.
- I find this in my journal: pulseaudio[26009]: Assertion '!u->thread' failed
at modules/bluetooth/module-bluez5-device.c:1731, function start_thread().
Aborting.
- It's interesting that PulseAudio since then has been saying this when
running it: N: [pulseaudio] main.c: User-configured server at
{2956b849822048eabdf5bd169ef03d78}unix:/run/user/1000/pulse/native, which
appears to be local. Probing deeper.
Things I tried:
----------------
- Rebooting
- Removing device then pairing again
- Check for any bluetooth-related or pulseaudio-related updates
- Checked permissions on /run/user/1000/pulse/native</pre>
