Chapter 4 is a software programming reference designed to aid in the development of High Definition Audio compliant software, including controller and codec programming. Codec hardware designers and software programmers will find this chapter of interest. When a plug is inserted, the stereo signals contact the respective channels on the plug and are disconnected from the jack’s return pins.
When the plug is inserted, the isolated switch 88 the jack informs the motherboard, and the codec sends audio to the headphones. Fab 11X ISO Information on codec architectural building blocks, as well as the software programming model, is provided.
Likewise, some modern enclosures have both an “AC’97” and an “HDA” alc8880 at the end of the front-panel audio cable. Designers of controller and a,c880 hardware will find this chapter of interest. Chapter 6 describes the physical link electrical requirements necessary for interfacing High Definition Audio controllers with codecs on the link.
Retrieved 14 January 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. Even though the actual audio hardware is HD Audio, it will allow using the AC’97 front panel that way.
For the marketing term HD audio, see High-resolution audio.

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. In the AC’97 design, the audio output is always sent to the jack. A similar isolated switch is used to detect when a microphone has been plugged in. Intel High Definition Audio also called HD Audio or development codename Azalia is a specification for the audio sub-system of personal computers.
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 slc880 insure that the jack detection and dynamic re-tasking 8882 is preserved.
