[Fedora-music-list] fedora 12, Pulseaudio and Jack

In Fedora 12 with Planet CCRMA Jack Audio Connection Kit, does starting jack with qjackctl suspend pulseaudio? If not, how can I add pulseaudio suspend (and resume) to qjackctl? How can I tell if pulseaudio is running, is there a terminal command for pulseaudio status? I have searched through the jackaudio.org, pulseaudio.org, qjackctl.sourceforge.net and other sites, and didn't find an obvious answer. http://fedorasolved.org/Members/fenris02/pulseaudio-fixes-and-workaroundshas some info but not about jack. Thanks, Jeff Sandys
