Should play these if not then Windows Media Player is not the default player for WAV file association .
Open Windows Media Player, Click On Windows Media Player icon at the top in the corner>tools>options>look under the file types tab>put a check mark next to Windows audio file (wav)> click Ok
Now try the file
(usually I have all of the files types selected as I prefer Windows Media Player as the default player , however you may have another like itunes, realplayer , etc)
