Yeah this is kinda a problem with the XDG startup scripts. PA is not
being spawned per-se, but rather started at startup via the scripts
"start-pulseaudio-*" (there are two)

I've tried to bring this subject up a while ago to get it fixed
properly, but it's never been quite satisfactorily solved in my opinion.

IMO a per-user PA should refuse to start if a system-wide instance is
detected, but it does not check this at present.

The quick and dirty fix is simply to edit the
/usr/bin/start-pulseaudio-* scripts and put and "exit 0" near the top.


If you want proper device lists in the Phonon configuration, you should
also edit your /etc/pulse/system.pa file and put a load-module command
for module-device-manager with the do_routing argument. This is what the
start-pulseaudio-kde script does, but as you will be preventing this
from running with your system-wide daemon, then you will have to set it
up manually.
