'sound' settings require changing device and back again

[Max Waterman]

I have two actual audio devices plugged in: 1. speaker under my monitor plugged into the 3.5mm headphone jack, 2. a set of USB headphones.

The 'Sound' settings panel shows three devices:
1. Headphones - built in audio
2. Digital output (s/pdif) - Jambra UC Voice 750 MS
3. Headphones - Jambra UC Voice 750 MS

(I don't really know what 2 is - I usually ignore it)

Normally, after plugging the headphones in, it has 3 selected, but the 'Test' button still plays through 1.

I have to change the 'output device' to 1, then back to 3 in order to make it work on 3.

So, this bug is that the control centre does not reflect reality when you launch it. It looks like it is automatically selecting the headphones just plugged in, but it hasn't actually changed.

Thank you for your bug report, could you report that upstream on https://gitlab.gnome.org/GNOME/gnome-control-center/issues ?

We're tracking a similar issue in 20.04 right now in bug 1866194 so let's use that until proven otherwise.

Also interesting the eoan and focal bug reports are within 2 days of each other.
