Unit Circuit Analysis and Testing
----Amplifier
Pin23: SDA Pin24:SCL Pin19: Mute Signal.
Pin1/46: Right Channel Output Pin36/39: Left Channel Output.
When the input signal and power supply are normal, but there is no output,
you need to check whether the back-end short-circuit or the amplifier was
damaged.
