Hi,
Not long ago (an hour or so) my headphone Jack stopped working properly and I don't know how to fix it. Basically when I put my earphones in the sound comes out of the speakers and on the left earbud. I've tried using a couple different earbuds so I know it's not them. Usually a little box pops up in the bottom right hand corner saying 'you just plugged/unplugged a device into the audio jack' and now it's stopped doing this.
