AMD SB600 AUDIO DRIVER

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. 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. Even though the actual audio hardware is HD Audio, it will allow using the AC’97 front panel that way. This page was last edited on 13 October , at List of digital television deployments by country.

In the AC’97 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.

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. Audio, mono, in mic. The motherboard can determine if the dongle is plugged in by examining the logic level on 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.

Not present, physical key. An AC’97 dongle returns audio on pins 6 and 10 rather than a digital plug audip signals. For the microphone jack, the return signal pins ground the microphone input when the microphone is not plugged in.

The different signal assignments can cause trouble when AC’97 front-panel dongles are used with HDA motherboards and vice versa. Interfaces are listed by their speed in the roughly ascending order, so s6b00 interface at the end of each section should be the fastest. For the marketing term HD audio, see High-resolution audio.

Features of the specification include: When a plug is inserted, the stereo signals contact the respective channels on the plug and are disconnected from the jack’s return pins.
