Realtek HD Audio on the sound card drivers to resolve installation failure
1, to enter safe mode (or the corresponding file will automatically restore the driver);
2, into the X: \ win \ sys32 \ drivers, delete Hdaudbus.sys, Hdaudio.sys (hda head and deletions, if there is, remember the following in the drivers);
3, enter the Device Manager. First out in the opening of the “Microsoft UAA Bus Driver for High Definition Audio”, this time the device will hit the yellow exclamation point. This again will be able to successfully deleted from the system to delete the hd bus driver, and (the voice of that out of Safe Mode not to delete the bus equivalent to delete it);
4, restart to return to normal mode, the familiar “Found New Hardware” screen on the back to you, first of all cancel, and then immediately install the corresponding version of driver Realtek HD sound card now. The last will not be a conflict.
5, the installation is successful, restart the system audio icon shows that the normal audio player.
Reasons: HD Audio driver is to be divided into two tiers: bus driver (Bus Driver) and function-driven (Function Drivers), “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. ”
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. For example, the HD on the Realtek sound card drivers windows HD in the absence of bus will be prompted to install the “Audio HD Driver installation failed” message and the sound card Device Manager will show the “Microsoft HD Audio” (hereinafter referred to as “win sound card “can not uninstall, do not provide audio capabilities), and the kb888111 fix this bug patch (released January 2005) was already in the machine, and can only be uninstalled first (it has been to Taiwan before the time I uninstalled, re – After the uninstall can not be installed), means that the patch can not be cut way to remove bus driver; then reinstall the system for example, in the case of the HD bus windiows first installed and then installed the sound card drivers, such problems will occur. Therefore, Microsoft’s own on OK to delete, and of course there are many solutions to many, this is what I tested, and rest assured rest assured that there is no problem!
