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.

expansion card.
