I am having trouble with my desktop playing back or recording mp3's. I have not previously had problems with it. I can play the song in wma format but when I try to play the mp3 it shows the music bars in windows media player or what ever I am using to play back but there is not sound. I have a XPS 400 with XP with media center. If anyone has any idea of what could be causing this I would appreciate it.

 

Thanks

Dennis
