I would like to have all the sound go through my left headphone

I would like for all the sound to be channeled through just my left headphone. The reason for this is a little odd, but I am completely deaf in just my right ear. It is incredibly annoying to hear games or video sound through just the left, because the left right differentiation is very different in real life. I looked through the audio settings and couldn't figure it out. If possible I don't just want the left sides audio, I would like the left and the right to be played through the left.
