The S/PDIF connector is used to connect an external S/PDIF port. Your S/PDIF port may be
mounted on a card-edge bracket. Install the card-edge bracket to an available slot at the rear
of the system chassis then connect the audio cable to the S/PDIF connector. Make sure pin 1
of the audio cable is aligned with pin 1 of the S/PDIF connector.
