You may also want to start qjackctl with its default settings and see
how that goes. Delete QjackCtl.conf and .jackdrc

Is this a USB sound device by any chance? If so, you should use -n3
(according to the man page). Is it the only sound card in the computer,
or are there multiples? What soundcard do you have (lspci can tell you,
if it's not a USB device).
-p512 is fairly small, although it works for my M-Audio Delta 1010LT.
Try -p1024 or -p2048. I don't think that's the cause of your problem,
but it's easy to try.

These next two lines are what I'd try searching for on the internet:

Is pulseaudio running? I've seen that give problems to some people,
although it didn't affect my usage. I can use jackd with or without
pulseaudio.

I guess that makes sense. Even if there is a jackd process, it
apparently isn't running properly.
