Hello Riccardo,
I read all post but i didn’t find the way to solve my problem I got.
The problem is, I have 9 editing suites with FCP 6.05 on Mac Pro with Aja Kona LHe. Some time, when I play the timeline, the audio wil go out of sync from video, it looks like the audio file is playing slower than the video file so the longger i play the timeline more duration of delay audio from video. It happen intermitten, and all suite ever faced the problem.
Some time but rare, shut down the machine will automaticly fix the problem.
I also have another suite with the same version FCP and the same Mac Pro tech spec but use Decklink HDExtreme3 as Video/Audio I/O card. Use this cheaper card but never face this problem 🙁
Help me please..
Olwin
