Front panel audio header This header is for a chassis-mounted front panel audio I/O module that PIN 1 supports HD audio standard. Connect one end of the front panel audio I/O module cable to this header. A_GND NC SENSE1_RETUR SENSE2_RETUR • We recommend that you connect a high-definition front panel audio module to this header to avail of the motherboard's high-definition audio capability. • If you want to connect a high-definition front panel audio module to this header, set the Front Panel Type item in the BIOS setup to [HD Audio].
