18) F_AUDIO1 (Front Panel Audio Header)
The front panel audio header supports Intel 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.
