Back on 10.3 I used a Rogue Amoeba program called Detour (I think) that allowed you to control which audio devices played audio from which software programs. I used it to send iTunes music through a USB audio device to powered speakers while playing Office apps noises through the built-in speaker. They discontinued it with 10.4 because Apple changed the way audio is handled. Question: Is there some similar app that maybe let's you control volume of each audio-emitting app? So I could turn Office all the way down (all those grating save chimes are killing me) while keeping iTunes all the way up? Thanks!
