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!

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.
