Audio suddenly stopped working on my SL100. Menus are navigable (no sound there either), already tried powering off, leaving the battery out overnight, tried several docks (including my boombox), nothing. Anyone else experience this? If so, can something be done or is the unit pretty much done? Thought of getting a SL2 but the guides are different (I remember seeing a few write-ups on how to make SL100 docks fit SL2). But what about my boombox (can the metal guides be removed)?
