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 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.

For HD Front Panel Audio:
For AC'97 Front Panel Audio:
• The front panel audio header supports HD audio by default. If your chassis provides an AC'97
front panel audio module, refer to the instructions on how to activate AC'97 functionality via
the audio software in Chapter 5, "Configuring 2/4/5.1/7.1-Channel Audio."
• Audio signals will be present on both of the front and back panel audio connections simultane-
ously. If you want to mute the back panel audio (only supported when using an HD front panel
audio module), refer to Chapter 5, "Configuring 2/4/5.1/7.1-Channel Audio."
• 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.
10) CD_IN (CD In Connector)
You may connect the audio cable that came with your optical drive to the header.
