Errrr.... I think (hope) Eric was simply announcing that he has identified that the clicks are related to the DDS tuning. I don't think he's thrown in the towel just yet. I'd still like to know why this hasn't been reported before (are others hearing it too) and if there is a solution. Seems like this merits a bug report to me!
