MP3/WMA won't play

[digitarian]

Hi,
I just purchased a digital voice recorder that records in MP3 192kb/s, 128kb/s, 48kb/s, and in WMA High Quality, Standard Play and Long Play. When I transfer the files to my computer, only the MP3 192 and 128 (both stereo) will play out loud on Windows Media Player and the WavePad Sound Editing software that I have on my machine. All the other formats seem to load O.K. and appear to be playing properly when I click the play button, except that no sound comes out. Any ideas?
I'm running Windows 7 home edition.

Thanks,

Gord

Maybe you need to select mono? Try some other players.
