Bill, Thanks for your reply. No, the slider does not stay put, only if you hold it in place. When you let go, it inmediately begins jumping back up to max. Upon quiting skype it returns to its previous setting. Very strangd!!! No other devices attached. Anyway the distortion is not so bad that you can't hear anything, but it does make it difficult. I've been on the road for a couple of weeks and just got back on line. Barry
