S/PDIF Information
S/PDIF (Sony/Philips Digital Interface) is an audio transfer format interface. It transfers digital audio signals from one device to another without the need to first convert to an analog signal, which can degrade audio quality.
Intel® Desktop Boards can include an S/PDIF port on the back panel or an S/PDIF header on the board itself. Refer to the Technical Product Specification for your desktop board to see if it includes S/PDIF support. If your desktop board doesn't include S/PDIF, you can disable onboard audio and install a sound card that includes it.
S/PDIF on the back panel
The image below shows the S/PDIF Out optical port on the back panel of a desktop board. Some Intel® boards also include an S/PDIF In optical port.
S/PDIF onboard headers
Intel Desktop Boards use either a 4-pin or 3-pin S/PDIF header.
You can connect a back panel S/PDIF bracket to the onboard header, similar to the one shown below:
You can also connect the onboard header to an S/PDIF input header available on some graphics cards using an S/PDIF cable. This connection routes digital audio to the HDMI output of the graphics card.
Typically, if the graphics card supports S/PDIF connections, the S/PDIF cable is included with the card. Connect the cable from the port on the graphics card to the S/PDIF Out and Ground pins on the desktop board. See the documentation that came with the graphics card for complete configuration instructions.
S/PDIF header pin-outs
Intel Desktop Boards use either a 4-pin or 3-pin S/PDIF header.
