Hi Rene,
I think you can safely factor the mixer out of the equation, unless you believe in voodoo ;-)
Pd doesn't play well with Coreaudio or Portaudio at all, so using JACK is the best workaround for that. Lots of archive discussion on this topic, but no solutions...
Best, Derek

i'm running into a strange problem with a particular mixer, a behringer dx626. I've got the headphones/lineout of my intel macbook (running os 10.6.2) connected to one of the line-ins on the mixer.
audio playback through the mixer works fine from itunes or from the finder.
when i switch to pd, however, audio keeps switching on and off at a rate of about 2 or 3 times a second.
i've tried fiddling with the Pd settings to solve this, but have not been able to find a solution so far.
i'm using portaudio, sampling rate 44100, delay 50ms, no callbacks, input and output devices are set to built-in mic& output.
changing any of these settings does not make any difference.
tonight i installed jack and this did solve the problem. while i'm glad i've found a solution, i hate not understanding why it works.... anyone any suggestions or pointers? :)
