So I know my studio headphones work (tried them from other sources). I have the correct adapter, but no sound comes out from any place when I plug the headphones in. We've had the piano 3.5 years (purchased new) and the input has never worked. It didn't matter before, but now my daughter wants to use the headphone feature because she will be in a dorm in college. I tried the rubbing alcohol/toothpick and q-tip trick as suggested for the reversed problem. No luck. Any suggestions? We live in Central Illinois and there arent any Casio dealers near us. I called corporate, but their only suggestion is the factory reset which doesnt work.
