8) F_AUDIO(FrontPanelAudioHeader)

The front panel audio header supports Intel High Denition audio (HD) and AC'97 audio. You may con-

nect your chassis front panel audio module to this header. Make sure the wire assignments of the mod-

ule 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.

• 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 assign-

ments, 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 expan-

sion 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 dis-

play 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 ex-

pansion card.
