Abstract
An apparatus and method are disclosed for controlling an audio output of an audio system to prevent a sudden burst of an audio signal through a speaker from startling people near the audio system when an earphone is disconnected from the audio system. By muting an audio output of the audio system when the earphone is disconnected from the audio system, such a sudden burst may be avoided.
