The combination of these technologies marks an important milestone in delivering quality digital audio to consumers.

A generic driver is used for systems that don’t have dedicated drivers. 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.

The different signal assignments can cause trouble when AC’97 front-panel dongles are used with HDA motherboards and vice versa. Post 6 of inttel Useful features include standard Universal Audio Yigh drivers from Microsoft and Sensaura with installed drivers from Realtek. Many laptops and motherboards don’t support jack sensing. Likewise, some modern enclosures have both an “AC’97” and an “HDA” plug at the end of the front-panel audio cable. Bump, I really need some answers guys!


Thank you for understanding. Most AC97 sound solutions, however, were optimized for low cost and space consumption, and that’s what they sound like.

The HDA driver supports: HD Audio can sense the presence of an audio dongle. When the plug is inserted, the isolated switch inside the jack informs the motherboard, and the codec sends audio to the headphones.

This produces higher-quality input to voice recognition, voice over IP VoIPand other voice-driven activities. High Definition Audio will not only provide an enriched playback experience but is intended to uadio a better-quality input for voice and communication applications. Consumers also want the ability to play back two different audio tracks simultaneously, aaudio as a CD and a DVD, which can’t be done using current audio solutions.
