This connector is for a chassis-mounted front panel audio I/O module that
supports either HD Audio or legacy AC`97 audio standard. Connect one end
of the front panel audio I/O module cable to this connector.
• We recommend that you connect a high-denition front panel audio
module to this connector to avail of the motherboard’s high-denition audio
capability.
• If you want to connect a high-denition front panel audio module to this
connector, set the Front Panel Support Type item in the BIOS setup to
[HD Audio]; if you want to connect an AC'97 front panel audio module
to this connector, set the item to [AC97]. By default, this connector is set
to [HD Audio]. See section 4.4.6 Onboard Devices Conguration for
