You know what? This is called active-waiting, and is BAD.
But I don't see any better option.

I would consider putting find-fifo's content's into echo-pause. It saves
one bash startup ;)

Well, something really good would be to pause everything on echo-pause.
I mean detect ALL MPlayers, pause these that are running (No idea how).
and pause xmms as well. This would be closer to 'incoming call, let's
make everything quiet'
