21) F_AUDIO (Front Panel Audio Header)
The front panel audio header supports High Definition audio (HD). 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.
•
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.
