I have searched but have not found answer this. I'm sure its simple - and I am stupid but.... Every 80kbps file I download will not produce a sound. When I play the file on any of PC players, the progress bars move left to right indicating the file is playing, but no sound comes out. Why? Also I cannot convert these kpbs files to WAV files. Is there some type of setting I need to make? Other than this every non-corrupted file I download works fine. Thanks for any suggetions.
