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.

For  AC'97 Front Panel Audio:

For HD  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 functioninality
via the audio software in Chapter 5, "Configuring 2/4/5.1-Channel Audio."

• When using an AC'97 front panel audio module, you can use either the front or the back

panel audio connectors, but not both at the same time.

• 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.
