10) SPDIF_O(S/PDIFOutHeader)
This header supports digital S/PDIF Out and connects a S/PDIF digital audio cable (provided by expansion
cards) for digital audio output from your motherboard to certain expansion cards like graphics cards and
sound cards. For example, some graphics cards may require you to use a S/PDIF digital audio cable for
digital audio output from your motherboard to your graphics card if you wish to connect an HDMI display
to the graphics card and have digital audio output from the HDMI display at the same time.
For information about connecting the S/PDIF digital audio cable, carefully read the manual for your expansion
card.
