There is an Intel® standard 10-pin AC’97 connector and an Intel® 10-pin HDA (High Definition Audio) connector
linked to the front panel of the case.
You can connect either the AC’97 or the HDA connector, depending on your motherboard. Locate the internal audio
connectors from your motherboard or sound card and connect the corresponding audio cable. Consult your
motherboard or sound card manual for the pin-out positions. Even if your system supports both standards, only use one
connector.
