Here is a list of the header AUDIO1 pin assignments.
USB2/USB3: Front panel USB Headers
The motherboard has USB ports installed on the rear edge I/O port array.
Additionally, some computer cases have USB ports at the front of the case. If
you have this kind of case, use auxiliary USB headers USB2/USB3 to connect
the front-mounted ports to the motherboard.
1. Locate the USB2/USB3 header on the motherboard.
2. Plug the bracket cable onto the USB2/USB3 header.
3. Remove a slot cover from one of the expansion slots on the system
chassis. Install an extension bracket in the opening. Secure the
extension bracket to the chassis with a screw.
IR1: Infrared Header
The infrared port allows the wireless exchange of information between your
computer and similarly equipped devices such as printers, laptops, Personal
Digital Assistants (PDAs), and other computers.
1. Locate the infrared port-IR1 header on the motherboard.
2. If you are adding an infrared port, connect the ribbon cable from the
port to the IR1 header and then secure the port to an appropriate
place in your system chassis.
