Raine,
Thank you. "du -m /dev/shm" shows 320 megabytes of memory locked out by
pulseaudio, even after its processes have been killed. So my mileage did
not vary at all.
Are you putting the "/usr/bin/pacmd exit; rm /dev/shm pulse*" script into
the qjackctl>Setup>Options box? The default script has long been
"artsshell -terminate" which I always thought was to kill the ancient KDE
arts daemon. If so, that option could use an update. 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?
Again many thanks,
John
