I added the two lines, installed the module and restarted pulseaudio.
BTW has same problem other daemons had of not detecting their pid file. 
Ooollld  bug.

Using ogg123 without any -d alsa: Works without jack running. Not with jack 
running. There is now a messagb dbus daemon around which is taking a lot of 
resources, idle, which pulseaudio apparently uses. Cannot start it without 
that.
