I'm posting for a friend's machine, so bear with me if I don't have all the details up front. The long and the short of it is...
Whenever my friend tried to play mp3 files on his machine, they play too quickly. This occurs with the inline windows media player as well as 3rd party mp3 players (music match and winamp). I figured it must be a system setting somewhere, but I couldn't find it. Any thoughts?
