Ubuntu needs a lock feature in the gnome sound settings, because each
time a device is detected the output/input will change automatically.
Sometimes this feature is wanted (I plug-in a headphone) sometimes it's
not (I don't want the sound output to switch to my monitor when I power
it since no speakers are plugged to it)

Audio output device changes upon unlock/login

Incomplete
Status in pulseaudio package in Ubuntu:

Bug description:
I have a ThinkPad X250 and updated To Ubuntu 19.10 today from 19.04.
Locking/Suspending and logging in changes my audio output device.
This did not happen in 19.04.
==== How to reproduce ====
When I lock my session with key combination "Win+L" and then unlock it again,
the sound that's been playing through my headphones/speakers stops playing.
When I check the audio settings, "HDMI/DisplayPort 2 - Built-in audio" is
selected.
When I select "Headphones - Built-in audio", sound continues playing.
There is no related log output in dmesg.
