Mac Pro adds Audio Crackle to DVCPro HD via Firewire

Hi folks,

We've been chasing down an audio issue with Panasonic for the past three weeks and we have finally determined it is the Mac Pro Quad 3.0 that is causing the issue.

What happens is a high end audio crackle, like sizzling bacon or crinkling cellophane, is added to the audio when mastering out to the Panasonic 1400 deck via Firewire. Via HD-SDI through the Kona 3 everything is fine.

We finally moved the project and the deck to our Power PC Quad G5 and the issue went away. Went back to the Mac Pro and the issue reappears.

Our audio engineer feels it is a word clock issue with the Mac Pro and we're going to see if we can fix this on our end. I'll update you if we get a fix.
