I'm having an issue with my Headphone Jack. I'm not sure if it's the jack itself our something else but when I plug a pair of Headphones into the jack only sounds comes out of the right side I've checked my Volume controls and done a test no sound out out the left when I do the test all the sound comes out the right side. However when I use a pair of Headphones that has a USB plug the sound comes out just fine it's only when I use the actual headphone jack that I have this issue. This leads me to think that there might be a problem with my headphone jack anyway I can fix it?
