Not quite enough info, does it sound like zipper noise or does it only happen when you turn the volume up on something? Without knowing more I can only suggest you bring all the faders down, (group all) this way you won't have to change all the automation moves. You can highlight all the channels, put them in volume edit mode and drag them all down 5db's or so. Select a point after the end of the song, make sure they all go down beginning to end not just another breakpoint.)
