All you have to do is use a file manager like astro. What you do in the file manager is search for your song, which ever one you wish to listen to. Once you find it, long press on it, then select open as, then select video, then select video player and that's it. Once in the player, you are able to listen to your song and press the "5.1" button and it does work. I'm still not sure if it sounds better with it on or off but neat to try.
