No sound from right headphone

Im using an asus laptop with realtek hd audio sound card and the minimum i can play is 44100 hz 16 bit and the headphones im using only play sound from 20 hz to 20000 hz but i can hear everything perfect in my left ear but nothing at all in my right. im wondering if there is anything i can download to play sound in both my ears cause its very annoying only having 1 ear bud available to listen through

If you are using Windows Media Player, try selecting the following options (make sure there is a checkmark next to it):
View -> Enhancements -> Show Enhancements
Then a section of the main display window will be taken up at the bottom showing words such as "SRS WOW Effects", "Crossfading and Volume Leveling", "Color Chooser", "Video Settings", and "Graphic Equalizer". You are looking for the "GRAPHIC Equalizer" - don't ask me why the programmers chose to use this name. Anyways, at the "GRAPHIC Equalizer", push the "Reset" button.
