Bug#898532: gnome-shell: Audio device selection

Package: gnome-shell
Version: 3.28.0-1+b1
Severity: normal

Dear Maintainer,

unplugging an HDMI device leaves the system in a state in which the device
presence is not reported anymore in Settings -> Sound, yet the system doesn't
switch to the computer built-in audio (sound card) and, besides, it is not
possible to perform this switch from Settings -> Sound.
It is necessary to have another sound device presence to get back to the
computer built-in device for sound output.

I would expect to system to switch to and from external HDMI output
automatically as it is done for video. If not possible I would at least expect
the possibility to force built-in audio as sound device once the HDMI external
device gets disconnected.

As a side note, my opinion is that if the switch isn't handled automatically,
then it's not handy enough to have to open Settings -> Sound to perform it (I
compare the situation to the video switch which is finely handled using
function keys).

Best Regards, Carlo.

Best Regards,
