The Classic II I just sold, has bad sound. The internal speaker is inaudible. With external powered speakers, you have to turn them all the way up, and then it is barely audible.

I pulled the board, and discovered it has some kind of blue wire going from a pin of one of the chips, to a little hole in the motherboard.

In the picture, I have drawn a blue line over the actual wire, in order to help you see it's path more clearly.

It seems to be held down with little globs of glue or something. It looks very professional, but I have no idea what it's for.

Will cutting it fix the sound? What about replacing capacitors - if replacing one cap would help the sound, which one would it be?
