I tried to switch internal sound like Jeremy told and no changes. I have same clicks. I actually e-mailed to aja support about 2 month ago. They promised to find it out. Until now there is no feedback. It can’t be my powermac I think because there wasn’t any problems when I used Decklink extreme before. If the clicking is normal to Aja I’m really surprised that until now no one really have claimed about it in this forum. I have talked to other editor who uses Kona LH and he has experienced same sort of thing but not as critical as mine.
Is it possible that it has something to do with electricity if its not grounded well or not grounded at all.
