The best way is if the program has been written to output it's audio
to jack, using the libjack api.

Another way is to make an audio pipe, where you have a program/system
that creates two virtual audio devices, where the output device sends
the audio to the input device. If you have something like that, you
can make the output driver the default audio output device (all
programs sends to this device), and let jackd connect to the input
device. Maybe soundflower can do that, or maybe some other software.
You'll have to look around.
