Public bug reported: On Ubuntu 20.04, once a bluetooth headphone is connected, it is not possible to use a different device output from settings page. In particular, despite the list has been populated properly, any selection apparently does not effect the system. Once the bluetooth device is disconnected, everything goes back to normal, giving possibility to switch between different sound devices.
