You have to make PulseAudio work on top of JACK if you want them both
running at once. Running JACK on top of PulseAudio is not supported at this
point. (It should theoretically work by enabling JACK's PortAudio backend
now that PortAudio works with PulseAudio, but you'd be going through 4
layers JACK->PortAudio->ALSA->PulseAudio, so it isn't quite ideal for
JACK's real-time requirements. And I have yet to test this - Fedora's JACK
currently isn't built with PortAudio enabled.)

Just the first one I found.
