When some times i trigger some clips,audio stops for some msec and the cpu goes to 100% and i hear clicks.Second time all is ok.This happen with midi and audio clips.
Any idea why is this happens?
I use macbookpro 2Ghz 2GB with a presonus firebox audio card.
Live 5.2 and with 5.2.1 intel version.

try a higher audio output buffer.

or try using the onboard sound. if you get no glitches, then the problem is with the Presonus.

I use 512 buffer.
Thank you i will try it with onboard sound.
