I'm having repeated trouble with my Sansa in my Sandisk dock. The problems have come and gone over the past couple years but right now I am uynable to play while in the dock. Songs will start for anywhere from a few seconds to a few minutes and then stop. The screen then indicates "connected" as if it were connected to the PC. I have seen this before periodically, usually when starting up or shutting down. I should be having these problems with a Sandisk dock. I have made sure the software is up-to-date on my player. It works fine with earphones. Any ideas?
