I recently had to re-install league cause the game would not open. But now while im in game. If my character is on the top half of my screen sound is normal. but if my character is on the bottom half the sound is so quiet i cant hear it. Its only the sounds my attacks and spells make though, everything else is normal. It does this if i look at an enemy or an ally as well.

Method,

It sounds like this is a surround sound issue. Are there sound settings in the in-game options or with your sound card that you can play with?
