You seem to be right: if I log into a console, and I start pulseaudio
(as it does not start by itself in this case) with systemctl --user
start pulseaudio, then both mic/sound are correctly muted.

What is maybe weirder is that if afterthat:

- I close my console session
- I open a gnome session

Then in this case, the mic/sound remains muted in gnome.

In log files, the difference between when it works and when it does not
seems to be the bolded lines, that are not printed when it works.
