How to use jackctl from command line?

There should be no problem running jackd, the jack daemon from the
command line. I do it all the time for my RME Multiface.

Note, though, you should not be attempting to use jack with the same
hardware sound device that you're using for speech-dispatcher or for
espeakup. That won't work.

I launch jackd like this:

#jackd --sync -X alsa_midi -dalsa -dhw:4 -r48000 -p256 -
jackd --sync -dalsa -dhw:4 -r48000 -p256 - 2>&1 &

More info on the jackd man page.
