Connecting the Audio Ports (AC’97 and HDA)

There is an Intel standard 10-pin AC’97 connector and an Intel 10-pin HDA (High Definition Audio) connector; you can connect either the AC’97 or the HDA connector to your motherboard depending on the spec of the motherboard. If your motherboard supports Intel’s standard onboard AC’97 audio connector, plug in the AC’97 connector directly onto the board. If your motherboard supports Intel’s High Definition Audio, you can plug HDA onto the board. See instruction below:
