Audio discussion : QJackCtl connections

Hi
I'm trying to use Jaaa or Japa (two FFT sound analysers in real time which are in our dependancies) with a playback coming from different sources like VLC or Audacity.
I'm using QJackCtl, the graphical interface for jack-audio-connection.
I used Jack before on an Apple and in the input (the left column in my capture), I had in "System" 4 outputs : the 2 playbacks and the 2 lines in.
As you see in my capture, this is impossible to me to connect the playback of VLC or Audacity to Jaaa or Japa via Jack audio to make it work.
Is there anything wrong with my sound parameters in "system preferences" as I only have the line in or microphone for choice.
In other words, how can I make work Jaaa or Japa via Jack audio with a VLC or audacity playback ?
Thanks a lot.

I have forgot to say that is is impossible to connect the pink and white lines of japa with the playbacks 1 and 2. Nothing will happen
vlc has a jack audio output plugin in the repo.
theres also a pulseaudio jack package or a package that has the bits
needed to connect pulseaudio to jack. i forget the name. i think you can
guess search in synaptic.
hope that helps.
Thanks for making me discover Jaaa and Japa.
I second the vlc plugin for Jack.
But I would avoid mixing pulseaudio with Jack.
As for the "Entrée", so there is the mic input. To me it's normal, I mean I don't expect to see anything else.
But I'm no expert at this.
Hopefully with the vlc plugin, vlc will appear in Qjackctl, and you might be able to connect vlc to Japa in "clients en écriture". At least that's what I understand.
