Bug Description

The dummy output in gnome-contol-center (g-c-c) will exists if

- no built-in speaker
- no headphone/earphone plugged
- using display (like VGA, DVI) without audio out is plugged.

However, in bionic, it will disappear as the headset is plugged and selected.
After it disappears, a reboot won't make it appear again.

bionic:
  gnome-control-center: 1:3.28.2-0ubuntu0.18.04.6
  pulseaudio: 1:11.1-1ubuntu7.4

In Focal, dummy output won't disappear.

focal:
  pulseaudio 1:13.0-3ubuntu2
  gnome-control-center 1:3.35.91-0ubuntu1

I do like to know which is the *corrected* behaviors so I know which one we should work on.

Agree that it’s not a major bug IMHO.
