What is HD Audio.
HD Audio is a High Definition Audio (Hi-Fi audio) acronym, formerly known as Azalia, is Intel and Dolby (Dolby) companies to launch a new generation of audio specification. HD Audio was designed to replace the current norms of popular AC’97 audio with AC’97 have much in common, to some extent, it can be said that an enhanced version of AC’97, but it does not backward compatible with standard AC’97 . It is the basis of AC’97 providing a new connection bus, support for higher audio quality and more. AC’97, compared with the existing, HD Audio with data transmission bandwidth, and high precision audio playback, support for multi-channel audio input microphone array, CPU and lower the occupancy rate of the underlying driver can be generic and so on.

HD Audio driver is to be divided into two tiers: bus driver (Bus Driver) and function-driven (Function Drivers), the “bus driver” is the drive to achieve the most basic audio functions will be integrated into a unified operating system. In Windows XP, Windows Server 2003, and Windows 2000 system is the Microsoft HD Audio Bus Driver, generally known as the Universal Audio Architecture (UAA) High Definition Audio class driver. “Function-driven” is a special function to achieve the functional drive, including the audio control panel software, provided by the CODEC chip manufacturers.
In other words, when the HD chip winXP search system will be installed, bringing the bus driver, then if the chip plant in addition to the HD drive also includes features drive outside the bus driver, the conflict is coming.
