Simple question about JACK that I haven't been able to find anywhere else.

Hoping someone here's kind enough to set me straight. :)

Coming from PulseAudio, I noticed that JACK's documentation and discussions

seem to barely mention things regarding channels....but do refer to ports quiet

often. So I was wondering what kind of mapping there is between say L and R

channels and JACK ports? Or does a mapping even exists?

Thanks,

Hai
