Audio issue! SFX, specifically

[Twig]

There seems to be a problem with sound effects essentially not playing at all, unless they're off the screen. For example, when I should fireballs at people/monsters on the screen there's no sound at all, but if I fire from far enough away that they're just on the edge or even off screen, it'll play very loudly. Lots of effects act like this. Almost like the volume is inversely proportional to the player position/center of the screen!
