If you intend to use consumer applications like Flash or media players in your JACK setup, one possible solution is to use PulseAudio as an intermediate layer for all these non-native-JACK programs. Basically, it boils down to the following:

Redirecting PulseAudio to JACK

On Debian-like systems, make sure that you have install pulseaudio-module-jack.

apt-get install pulseaudio-module-jack

Then, add the following configuration to your pulse-daemon, if you intend to run jackd all the time:

nano /etc/pulse/default.pa
[ ... ]
load-module module-jack-sink
load-module module-jack-source
load-module module-null-sink

set-default-sink jack_out
set-default-source jack_in
[ ... ]
killall pulseaudio
