MacAutoMute is a simple Preference Pane that auto-mutes your Mac when the screensaver goes on. Therefore, the program mutes all your system sounds after a few minutes (this time depends on how you set the screensaver). Consequently, no notification sound will wake you up in the middle of the night just because you forgot to press the mute button.
