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.
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.
