The title pretty much sums it up. I have two Color Classics, and neither one has sound. The second one had sound when I first found it, but managed to lose it by the time I got home. I don't think this is a coincidence. It seems to me that something has probably come loose inside, but I'm not sure what. I have the pdf manual, but that's no big help for this one. A cursory check of the insides didn't turn anything up, so I'm looking here for ideas. I'm pretty good with a computer's insides, so I'm hoping someone here might have an idea of a path to follow.
