METHODS AND APPARATUS FOR CONTROLLING AUDIO VOLUME ON AN ELECTRONIC DEVICE

摘要

An apparatus and method for facilitating a user's interaction with an electronic device to control selected audio output volumes of the device. The described methods and apparatus facilitate operation of the electronic device with a volume limit for audio content output from one or more ports of the device that is less than the maximum output volume available from the device. A first user input to increase the volume of an audio signal at one or more ports will increase the volume only to an initial volume limit that is less than the maximum output volume available. A visual, non-textual indicator of the availability of additional volume levels will be displayed to a user; and subsequent receipt of a second input to increase the volume of the audio signal will cause an increase in volume beyond the initial volume limit.
