your chassis front panel audio module to this header. Make sure the wire assignments of the module
connector match the pin assignments of the motherboard header. Incorrect connection between the module
connector and the motherboard header will make the device unable to work or even damage it.
For HD Front Panel Audio: For AC'97 Front Panel Audio:
The front panel audio header supports HD audio by default.•
Audio signals will be present on both of the front and back panel audio connections•
simultaneously.
Some chassis provide a front panel audio module that has separated connectors on each wire•
instead of a single plug. For information about connecting the front panel audio module that has
different wire assignments, please contact the chassis manufacturer.
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.
