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.

Audio, mono, in mic. Like AC’97, HD Audio is a specification that defines the architecture, allc882 frame format, and programming interfaces used by the controller on the PCI bus and by the codec on the other side of the link. HD Audio can sense the presence of an audio dongle. For the marketing term HD audio, see High-resolution audio. Even though the actual audio hardware is HD Audio, it audoo allow using the AC’97 front panel that way.

Consequently, an HDA motherboard would not detect the presence of an AC’97 dongle with a disconnected pin 4.

Likewise, some modern enclosures have both an “AC’97” and an “HDA” plug at the end of the front-panel audio cable. Not present, physical key.

In the AC’97 design, the audio output is always sent to the jack. For the microphone jack, the return signal pins ground the microphone input when the microphone is not plugged in.

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.

When a plug is inserted, the stereo signals contact the respective channels on the plug and are disconnected from the jack’s return pins. By using this site, you agree to the Terms of Use and Privacy Policy. When the plug is inserted, the isolated switch inside the jack informs the motherboard, and the codec sends audio to the headphones. Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest.

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.

Technical and de facto standards for wired computer buses.

In AC’97, pins 2 and 4 are audio ground, but pin 4 is often disconnected. Computer motherboards often provide a connector to bring microphone and headphone signals to the computer’s front panel.
