I'm at work now, and we ~only have delta cards. At home I use a built-in
sound-card on an nforce chipset. But I get nearly the same good
performance in pd here as at home. So here is delta44 parameters:

Pd is v0.35, running as normal user, no special hardware options except
"-alsa".

k_jack
performs okey. You dont have to run things with realtime priority.
What does "cat /proc/asound/card0/pcm0[cp]/sub0/[hs]w_params" output
while you are running k_jack? This information should help us understand
the benefits of k_jack over current jackd.
