ABSTRACT:
An exemplary audio signal transmission circuit includes a codec to provide analog and digital audio signals; an amplifier connected to the codec to receive the analog audio signals; a control circuit connected to the codec to receive the digital audio signals and connected to the amplifier to selectively turn off the amplifier; a front audio port connected to the amplifier to receive amplified analog audio signals generated by the amplifier; and a rear audio port connected to the amplifier and the control circuit to selectively receive the amplified analog audio signals or the digital audio signals. The control circuit and the front audio port are turned off when the rear audio port is connected to an analog system, and the amplifier and the front audio port are turned off when the rear audio port is connected to a digital system.
