Methods and apparatus for enabling auto-recovery of a digital audio
amplifier after a short-circuit are disclosed. In accordance with one
embodiment, a short-circuit is detected by both detecting a switching
signal at an output of the digital audio amplifier and sensing a mute
signal coupled to the digital audio amplifier. Once a short-circuit has
been detected, a reset signal is provided to a reset input of the digital
audio amplifier when the switching signal indicates that the digital
audio amplifier is not switching and the mute signal indicates that the
amplifier is in an un-muted state.
