Bluetooth headset profile forgotten after disconnection

[Adam Collard]

Similar to bug 1283003, after connecting my Bluetooth headset (Sony WH-1000X M3) they appear in Gnome Control Centre's Sound tab but are not selectable.

I've narrowed down the circumstances to reproduce the bug as follows:

1. Start with working sound through Bluetooth to headset
2. In pavucontrol's Configuration tab, note that headset is listed with A2DP profile
3. Disconnect (power off) the headset
4. Note that sound comes out of fallback device (as expected)
5. Power on the headset and reconnect to Bluetooth
6. Look in Gnome Control Centre and note the headset appears in Sound, but is not selectable (buggy)
7. In pavucontrol's Configuration tab, note headset is listed with "Off"
8. Manually switch to A2DP
9. At the point, we have to cycle the connection again (disconnect/reconnect) and then sound is once more routed to the headset.

Status changed to 'Confirmed' because the bug affects multiple users.

[Daniel van Vugt (vanvugt)]

AFAIK, only gnome-control-center has any memory of user preferences. So reassigning there.

I stand corrected. There is also ~/.config/pulse
