During the game, sounds like your sword being swung, menu selections, item switching, etc. are played through the Wii-mote speaker, which is shallow and sounds cheap. Although it makes the experience have more depth, the sound quality of that depth is low. Press Home and turn the Wii-mote speaker volume all the way down to shut it off. All sounds will now play through your television or sound system, and will be of much better quality.
