unfortunately, head is not showing some output from jack.
you are missing this line:
creating alsa driver ... hw:0|hw:0|4096|2|48000|nomon|swmeter|rt
this is useful cos it shows how jack is actually running.
This particular line is sent to stderr, instead of stdout (which is what head would be
reading from). I'd suggest the following:
jackd -v -d alsa -d hw:0 -p 512 1> jackstdout 2> jackerrout
Let it run for half a second, and then kill it with Ctrl-c. Both files (jackstdout and
jackerrout) should contain more detailed information about what's going on.

# jackd -d alsa -d hw:0 -p512 |head -n 6
