Try increasing the -p value given to jackd (not the -p given to the
alsa backend), that's "Port Maximum" and shows up on qjackctl's setup

Jesse suggested this when I had trouble connecting clients to jack
and/or adding tracks in ardour which is basically the same thing. This
came up only when I started jackd with capabilities enabled on a lowlat
kernel.
