KeepSoundAwake runs in the background and plays a "silent sound" every 20 seconds to prevent the audio hardware from sleeping. This application is only useful for Powerbooks running OS X 10.1.2 or higher. It does not do anything for other machines. This application is designed to address a couple of problems that appear on Powerbooks running OS 10.1.2 or higher. Due to an issue in the design, the OS will sleep the audio hardware if 30 seconds go by without any sounds being made, even if the machine is plugged in.
