Not present, physical key. A similar isolated switch is used to detect when a microphone has been plugged in. Microphone bias Audio, right, in biased, mic. 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. High-definition television High-definition video Ultra-high-definition television. Intel High Definition Audio also called HD Audio or development codename Azalia is a specification for the audio sub-system of personal computers. The motherboard can determine if the dongle is plugged in by examining the logic level on pin 4.

When a headphone is plugged into the front panel jack, the audio signal goes to the headphones; the return pins are disconnected, so no audio signal goes to the speakers. Likewise, some modern enclosures have both an “AC’97” and an “HDA” plug at the end of the front-panel audio cable. In the Alf882 design, the audio output is always sent to the jack. 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.

Technical and de facto standards for wired computer buses. 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. For the microphone jack, the return signal pins ground the microphone input when the microphone is not plugged in.

Lac882 provides a specification for that header, but the signal assignments are different for AC’97 and HD Audio headers. Microphone bias Audio, right, in biased, mic.

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. The different signal assignments can cause trouble when AC’97 front-panel dongles are used with HDA motherboards and vice versa.

Even though the actual audio hardware is HD Audio, it will allow using the AC’97 front panel that way. An AC’97 dongle returns audio on pins 6 and 10 rather than a digital plug sensing signals.

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. For the marketing term HD audio, see High-resolution audio.

Intel High Definition Audio

If the headphones are not plugged in, the jack directs the audio to the return pins that are connected to the speakers. Retrieved 14 January In AC’97, pins 2 and 4 are audio ground, but pin 4 is often disconnected. By using this site, you agree to the Terms of Use and Privacy Policy. Features of the specification include: HD Audio can sense the presence of an audio dongle. In the HDA design, when the plug is not inserted, the codec sends the audio directly to the speakers the audio does not go out to the front panel and then loop back to the speakers.
