On the PS3, check this. While music is playing, hit the green-triangle button. In the icon list that pops up, go to the speaker in the top, left. The volume control that shows up, should be set to "Normal", not - or + anything. While setting it to plus will make it louder, it also causes horrible digital clipping. Minus will limit the dynamic range. Only normal, should ever be used.
