PA has a timeout that prevents it from closing immediate. This means that if PA autospawns, it will stick around for a little while in case it's needed again (while startup is fairly quick, we do have to probe the hardware so it does take time). This is primarily for console applications rather than X11 however, as under X11 a Session Manager module is loaded which keeps PA alive for the duration of the X session. You can make a change in daemon.conf to set exit-idle-time to 0. This should allow PA to exit when the X11 session exits.
