15) F_AUDIO (Front Panel Audio Header)
The front panel audio header supports High Definition audio (HD). You may connect 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.

16) 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.

17) CPU/DRAM/VGA/BOOT (Status LEDs)
The status LEDs show whether the CPU, memory, graphics card, and operating system are working
properly after system power-on. If the CPU/DRAM/VGA LED is on, that means the corresponding device
is not working normally; if the BOOT LED is on, that means you haven't entered the operating system yet.
