Multi-stream over single display port Document change notification covers multi-streaming over single display port 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.

Energy-efficient audio buffering and dynamic FIFO limit change Document change notification for energy efficient buffering specs, with changes Preview Download View For the microphone jack, the return signal pins ground the microphone input when the microphone is not plugged in.


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.

Computer motherboards often provide a connector to bring microphone and headphone signals to the computer’s front panel.
