12) 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.
