I have externally powered speakers connected to my Mac. When I boot up, the startup chime sounds loud and clear. So I set the volume accordingly. However, when I listen to any type of audio played on the Mac, the same setting is way too soft. For months now, I've been manually turning the volume up (on the external speaker controls) whenever I listened to audio, played back digital video, or just listened to stuff from the Internet. Then I must remember to manually turn the volume back down again for regular computer use. And if I forget, the next time I start up the CHIME becomes SUPER LOUD! Annoying! Especially for my sleeping roomate! All the combinations of software and hardware volume controls don't seem to strike a general setting. Am I missing something? How can I modify the boot-up chime so that it's softer? Or how can I eliminate it altogether? Its loud volume is the only one that's WAY out of proportion with everything else. Is there any other way to establish a general volume setting?
