    28  *  An interface to Global Audio Settings observer callback functions.

    29  *

    30  *  This serves as the method of communication between the client and the

    31  *  CGlobalAudioSettings object.

    32  *

    33  *  The class is a mixin and is intended to be inherited by the client class

    34  *  that is interested in observing the global audio settings. The functions

    35  *  encapsulated by this class are called when events occur which causes device

    36  *  audio settings to be changed that affects the overall audio behavior.
