Kona2 & audio crackling
I’m having a strange problem here. Every once in a while when I stop the CTI on the timeline and start it up again, the audio makes a crackling noise like distortion. But if I stop again and start it up again, its fine. I have the 1.12 drivers installed. Its not a real problem but its very annoying.

I have the same problem. If I go to the Kona Control Panel and switch the genlock from video in to free run it seems to help the problem.

Greg is correct – I don’t know why – it’s almost like a bug – the Kona 2 will “for some reason” – and there must be a reason – switch to Reference – Video In – by itself. Switch it to external ref (if you have an external ref) or Free Run, and your crackle will go away.

After playing with it for the past few days. I noticed that the sync on mine is already set to Free Run and I still get the crackling noise. I don’t know but its annoying when you have a client in house and have to appoligize for the noise. Usually have to just stop my program, then start playing it again and its fine. Its weird!

Interestingly enough I had this same problem on the BlackMagic Extreme as well. Never was resolved…
I wonder if it is some kind of FCP issue.
