I have a minor sound issue (headphones and speakers)

[Onilink]

i use winamp 5 (the newest version), and well my right side of my sound sounds fuzzy. i uninstalled and nothing works. i checked all my sound settigns and i see nothing wrong. i used windows media player, and it works fine, other sound (from aim, games, and what not) works as well. it only happens with winamp. anyone kno what could be my problem?
