Hello.The jack control application has some bugs in this version (in my experience), but it is still functional.In my case, i run the following commandQuotejackd.exe -R -m -dportaudio -dASIO::ASIO4ALL v2 -r44100 -p512That can be setup from jack control setting portaudio as the driver, and then looking (just looking) the name on the output device (selecting it will allow to copy the text).Leave the box as (default), and copy the name into the Interface box. The buttons on the right should allow to autoselect the driver,but they make the aplication crash.The patchbay is a place to store wiring configurations. It is a "preset manager" of sorts. The important place is the Connect, where you actually route audio.About routing audio between two applications, JACK2 (i.e the current JACK version, 1.9.x) has an ASIO driver. If you have the jack daemon running, you should see an audio device named JackRoute. I've only tried it as audio ouput (haven't tried it as input).Finally, there's another option that i haven't yet tried which is networked audio. You don't need this for the setup you describe, but would allow applications even in two different networked machines to send audio to each other.
