Well, that sucks. I'd like to use the speaker for music and the headset
for audio conferencing. It doesn't seem like an unusual setup to me and
having to connect/disconnect devices manually when someone calls me
feels like a lot of unnecessary hassle. But maybe I'm mistaken.

Could you find some reference or at least suggest some keywords I could
search on? I'm not that familiar with either Bluetooth or Pulseaudio.

Shall I file a bug against pulseaudio at the new gitlab issue tracker
(https://gitlab.freedesktop.org/pulseaudio/pulseaudio/issues/)?
