Sylvania MP3 GB player (SMPK2021) ver 3.120
I recently bought one of these, And I always keep it in safe places because my last one (of a differant brand, but it had the same problem, but that's only because the button somehow broke from the inside.). I don't know how, but just two or three days later, the sound stopped working. That is to say, it works, but it won't turn up or down, it's stuck on very low. The inside looks fine, I don't know what happened to it. I'd take it back, as the garentee(sp?) is still affective, but I lost the receipt. (sp? sorry)
