Retrieved from ” https: The different signal assignments can cause trouble when AC’97 front-panel dongles are used with HDA motherboards and vice versa. It is strongly recommended that motherboard designers only use Intel HD Audio analog front panel dongles with the Intel HD Audio analog front panel header to insure that the jack detection and dynamic re-tasking capability is preserved.

Many motherboards with AC’97 audio need two jumpers to short the pins in case no front panel audio module is connected, so audio passes to the speakers. From Wikipedia, the free encyclopedia.
