Comment 8 for bug 1814964

A quick Google shows some hints:

https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/SystemWide/

https://wiki.archlinux.org/index.php/PulseAudio/Examples#Allowing_multiple_users_to_use_PulseAudio_at_the_same_time

If we are to follow upstream's recommendations then that would make this bug "Won't Fix". Because the only solution they provide is also one they don't recommend.

However I don't find that conclusion satisfactory when probably no other OS has this problem. So I will leave this bug open.
