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. List of digital television deployments by country. Like AC’97, HD Audio is a specification that defines the architecture, link frame format, and programming interfaces used by the controller on the PCI bus and by the codec on the other side of the link.

When a headphone is plugged into the front panel jack, the audio signal 82 to the headphones; the return pins are disconnected, so no audio signal goes to the speakers. The motherboard can determine if the dongle is plugged in by examining the logic level on pin 4. In AC’97, pins 2 and 4 are audio ground, but pin 4 is often disconnected.

88 4 is a software programming reference designed to aid in the development of High Definition Audio compliant software, including controller and codec programming.

Consequently, an HDA motherboard would not detect the presence of ac880 AC’97 dongle with a disconnected pin 4. Fab 24 ISO Chapter 6 describes the physical link electrical requirements necessary for interfacing High Definition Audio controllers with codecs on the link. When the plug is inserted, the isolated switch inside the jack informs the motherboard, and the codec sends audio to the headphones.

Even though the actual audio hardware is HD Audio, it will allow using the AC’97 front panel that way. 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.
