/**
 * @classdesc
 * No audio implementation of the sound. It is used if audio has been
 * disabled in the game config or the device doesn't support any audio.
 *
 * It represents a graceful degradation of sound logic that provides
 * minimal functionality and prevents Phaser projects that use audio from
 * breaking on devices that don't support any audio playback technologies.
