Just let me say thanks to Linium and others:
The problem seems to have disapeared after i made jack use 48khz instead
of 44.1khz
I have to do some more testing, but it seems i can now drive my apps in
full-duplex without major problems.
Why the different behaviour of alsa and jack? I guess that was because
the app i mainly used for testing (ams) would set the sample rate to
48khz when using alsa and accept the preset rate (44,1khz) when used
with jackd. which lead me into the false assumption that there could be
something wrong with jack.
Glad that's solved! :-)
