ext/jackio.c aubio_jack_process

["William Robinson" <airbaggins@gmail.com>]

hi.

I was using the aubio jack support functionality from libaubioext, trying to use just the input. I found that it was crashing here in aubio_jack_process because it was trying to write to a non existant channel (as it assumed there that input channels == output channels). I've attached the change I made as a patch.

Thanks for this library.
:)

ciao

bill
