Hi everyone,

I'm having an issue with audio output in PD : when setting audio to output via portaudio, all the audio that gets out of PD has audio glitch in it, some kind of random-spaced crackles or clicks. It is completly useless as such. Increasing the delay in PD's audio settings doesn't change a thing.
However, using Jack as an audio outlet supresses all this problem, and the audio is clean that way.

Would anyone know the reason for this? I would be glad to know it as there may be a link with another issue about audio on my hardware : system audio of mac os X has the same kind of glitches that I got with PD on portaudio, only it's only occasional glitches so it's bearable. Solving this issue would be a big relief to me.

My hardware is a hackintosh (pc with osX installed on it), and mbox2 as audio interface (but I have tested with an m-audio transit and I have the same crackling issue). My soft is osX Snow Leopard 10.6.5.

Any help appreciated!

Doesn't anyone have a clue?
