An AC’97 dongle returns audio on pins 6 and 10 rather than a digital plug sensing signals. If the headphones are not plugged in, the jack directs the audio to the return pins that are connected to the speakers.
Consequently, an HDA motherboard would not detect the presence of an AC’97 dongle with a disconnected pin 4. 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.
Intel High Definition Audio also called HD Audio or development codename Azalia is a specification for the audio sub-system of personal computers. Even though the actual audio hardware is HD Audio, it will allow using the AC’97 front panel that way.
A similar isolated switch is used to detect when a microphone has been plugged in.

Likewise, some modern enclosures have both an “AC’97” and an “HDA” plug at the end of the front-panel audio cable. Flaming or offending other users.
Intel products Sound cards. 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.
