SPDIF stands for Sony/Phillips Digital Interface and is a port that utilizes fiber optics to send out an audio signal. Many ASUS motherboards have multichannel audio output capabilities, which is useful for surround sound setups. Instead of using individual cables for each channel, the SPDIF port sends out the audio signal for all of the ports at once. An audio receiver can then automatically decode the signal into the proper channels. The SPDIF port is automatically enabled when it is connected.
Instructions
1. Disconnect all of the cables from the colored ports on the back of the motherboard if you are using multiple channel audio. If you are not using multiple channels, disconnect the speaker cable from the lime colored port.
2. Connect a fiber optic cable from the SPDIF port on the back of the motherboard to a SPDIF input on the back of the audio receiver.
3. Turn on the computer and the audio receiver. Change the input on the audio receiver to the same one used in Step 2.
