7) F_AUDIO (Front Panel Audio Header)
The front panel audio header supports Intel High Denition 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 con-
nector 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 simultane- •
ously.
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 assignments, please contact the chassis manufacturer.
