9) F_AUDIO (Front Panel Audio Header)
The front panel audio header supports Intel High Definition audio (HD) and AC'97 audio. 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.
