Newer PA and JACK versions cooperate in this way
automatically. If you fire up JACK PA will go out of the way for that
device. And after JACK is done PA takes the device back. JACK is king
and PA will comply.

In older versions you can use a tool like "pasuspender". It will
suspend PA's access to the audio devices temporarily as long as child
process is running. If you make that child process JACK you have a
neat way to make JACK and PA not fight for device access.

A more brutal way is to stop PA with "pulseaudio -k" before you run
JACK and then start PA with "pulseaudio -D" afterwards. But that
probably won't work that nicely since PA is configured to autospawn in
most cases these days -- which you can disable however by editing
client.conf.
