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 HD Front Panel Audio:

For AC'97 Front Panel Audio:

• 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 simultaneously.

• 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.
