Since you are using the headphones with their own audio interface, they
are not used by JACK at all (I'm assuming your are using your internal
soundcard as the device for JACK). You have to route sound to them via
the pulseaudio-jack bridge. Then use pavucontrol to route the sound
within pulseaudio to the headphones interface. you might be able to
configure pulseaudio to do that switching automatically.

For your JACK clients (Audacious, etc.) to send their output to the
pulseaudio-jack sink, either use their UI settings interface - but then
you'll probably only be able to connect them to one output port pair -
or some tool for automating jack connections like the qjackctl patchbay,
aj-snapshpt, jack-matchmaker, jack-autoconnect or jack.plumbing.
