My apologies in advance if this is a)painfully obvious or b)in the wrong forum (as MacNN has seemed a bit chilly as of late), but is there a way to turn the sound off on an app-by-app basis? For example, if I'm listening to iTunes but then navigate to some website where somebody has background music playing, I'd like to turn that b/g music off. If it's not an OS functionality, does anyone know of any shareware that can do this?
Thanks,
MM
