When I play music from a USB drive on my standard MS sound system, I am experiencing skips. I have tried two different USB drives from different manufacturers with the same result. Then I tried playing the music on my computer from the USB drive and there are no skips. So I am assuming the problem is in my MS sound system. The file format is wma (windows media audio). I don't see anyone else on the forum having this problem. Any ideas for solving this problem?
