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.
