calling jack_client_open() to connect to the JACK server.
registering "ports" to enable data to be moved to and from your application.
registering a "process callback" which will be called at the right time by the
JACK server.
telling JACK that your application is ready to start processing data.

 it is JACK server call jack_process callback and pulseaudio server have to
supply enough frames
