Sound output only partially updates when connecting bluetooth device

[Dotan Reis]

When I connect a bluetooth device as sound output, either from bluetooth settings or just automatically, the sound starts coming from the bluetooth speaker, but in the sound settings the output is still set to the built-in audio.

This means that the volume buttons are useless (affect the built-in audio which isn't playing anyway) until I open the sound setting and fix this.
This happens every time.

When I switch output again, it affects both the settings and the actual output.

I expected the sound settings to match whatever output is actually playing.

I'm using Ubuntu 16.04 LTS. The bluetooth device is a DOSS soundbox
