So something is pretty badly broken in your setup - what did the members
of the PD mailing list suggest to fix this?
Without any information about how your jack is set up and how you run PD
it's pretty futile to try to help. On my humble box the following setup
works fine (and I _do_ use PD to do pitch tracking):
$ cat ~/.jackdrc
/usr/bin/jackd -P78 -u -dalsa -dhw:0 -r44100 -p128 -n3
$ pd -rt -jack

I wouldn't
like to de-rail this too much as there is a very active Pd
mailing list. Anyway.
Pd can take a while to get into, but I can say that Pd works very well
with Jack and I never had big issues. Of course you should keep in mind
that Pd is a programming language and enables you to do whatever you
want, even fill an array beyond your ram size et. sim. with great power...
That is crystal clear to me, yet I get xruns even at startup when
nothing is loaded to produce anything... >> And is there anybody who uses PD for the job

Jack audio is handled by the input parameter - start PD with the '-jack' switch.
You probably want the '-rt' switch as well (makes PD use realtime priority).

Just create a [adc~] object (that will provide audio from the jack input)
and connect it to the [sigmund~] input.

[sigmund~] out
PD doesn't have a Jack-MIDI out, only ALSA Midi so far. Just send your midi
note to an [noteout] object. You can configure the number of Midi inputs/outputs
from the menu or do it with a command line switch.

I'll do this on a regular basis, no problem.
