Thanks Raine. My current understanding is that artsshell -q terminate does in fact stop the pulseaudio processes but it does not release enough memory (by removing the contents of /dev/shm) to allow a second startup of qjackctl. The exact symptoms would vary with the amount of memory installed in a given machine.

I actually only did this cleanup from the command line so far, but that is the place where I'd put the commands. Any more commands and I'd migrate it to ~/bin/jack-prestart.sh or something.


I suppose the replacement script would need to be setuid, since at least
one of the pulseaudio files could not be removed as user. That in turn,
I think, means this needs to be a compiled program rather than a shell
script for security reasons. Does that make sense?

I wouldn't worry about that one file (left from playing some startup sound?) unless it actually causes problems. I'm of course assuming a single user setup, where there wouldn't be leftovers from other users' sessions.
