Trying again, maybe you will answer my other question too.

My normal use case is that I have rhythmbox running in my account which
I tend to screenlock, when my wife wants to browse the web briefly she
fast-switches to her account.

What will PA do? Will it stop rhythmbox in the other session? If so why?
What is the logic? I usually want to keep the music running.
