GNOME Bugzilla – Bug 693988
Automatically set correct sound settings on speaker bluetooth connection
Last modified: 2019-03-20 10:38:41 UTC
Pairing and connection of bluetooth headsets works fine. However when controlling audio volume it is necessary to go in the "Sound settings" dialog and manually select the bluetooth device. Ideally the bluetooth device should be automatically selected in Sound settings upon successful pairing/connection.
I can confirm this. My guess is that the sound plugin to gnome-settings-daemon doesn't notice when the output device is automatically set to the newly paired bluetooth device. If anyone could give me an initial pointer on how to fix this (is there any interface/signal that can be listened for? If not, is there a natural place (on dbus?) to add such a signal?) then I could probably produce a patch.
I just noticed this, now: One thing that isn't clear from the bug report is that sound output *IS* sent to the bluetooth device; it's just either the gnome-control-center or the gnome-volume-mixer that doesn't seem to know about it. So you'll have seemingly non-working volume control (it operates on a device that you're not actually hearing) right after pairing if you do not select the device in the UI, too. So in my opinion, this seems more like a genuine bug and less like just an enhancement.
#662382 seems to be the same issue. I'm not sure where in the interaction between gnome-bluetooth, gnome-control-center and bluez the problem lies.

Actually, this problem occurs with other sound outputs too, not just Bluetooth. I don't actually remember what sound source I was using, but it may have been a USB sound adapter.
