Consequently, a loud audio passage may make the HDA motherboard with AC’97 dongle believe that headphones and microphones are being plugged and unplugged hundreds of times per second. A similar isolated switch is used to detect when a microphone has been plugged in. Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest. Views Read Edit View history. The different signal assignments can cause trouble when AC’97 front-panel dongles are used with HDA motherboards and vice versa.

List of digital television deployments by country. For the microphone jack, the return signal pins ground the microphone input when the microphone is not plugged in. Intel provides a specification for that header, but the signal assignments are different for AC’97 and HD Audio headers.

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.

Features of the specification include: From Wikipedia, the free encyclopedia. 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.
