Portaudio's Jack support is completely borked. If you do not
intend to use its cross-platform features, please spare us
the misery of yet another Linux app using it.

Just use Jack's native API. When you've got that working, and
you want ALSA as well, use the zita-alsa-pcmi library. This 
will allow you to share 99% of your code for ALSA and Jack.
