Hi there,
I'm using a 828 MKII with a new Macbook unibody running os 10.5.6. Latest Motu drivers installed 1.4.20
I get lots of crackles when reproducing audio (mp3, video, system sounds, ableton live). I reinstalled drivers, changed USB cable, factory reset, tried different outs, changed power cable and tried on a Mac Mini running Tiger, but I got the same problem. No one answers me from motu support. I really don't know what to do. The issue disappears when using it in standalone unplugged from macs. Any suggestion? This thing is driving me crazy. sad.gif
Thanks.

Hello

Have you checked the audioMIDI set up?
Are the audio settings in system preferences ok?

Crackles are usually caused by: too much CPU strain (beef up the latency cache), the driver (seems you tried already), a bad clock/clock setting.

Also, as you are in USB, are there other peripherals in USB attached to the computer?
