Knowledge Point analysis:

Microsoft UAA (Microsoft Universal Audio Architecture) bus driver is Microsoft's system-level support driver for HD Audio standard HD Audio bus (High Definition Audio. The new HD Audio card driver and Modem driver are both developed based on the HD Audio bus.

 

This problem does not occur if you use the Lenovo random system to install the disc and use the Lenovo application function to automatically install the driver. This problem may occur if you use other system installation discs to install and hide damaged partitions. We recommend that you first check whether the kb888111 patch is available on the CD (for different sound cards, the kb888111 patch is generic). Install the patch and then reinstall the audio card driver. This patch was released on April 9, 2006 and is not included in the SP2 patch package. However, random system discs generally integrate some of the latest patches.


Procedure:

An error is reported when drivers are installed using HD sound cards (such as AD1986A sound card chip) and Modem: "HD Audio bus driver is required, but not found." The UAA bus driver is displayed in the Device Manager.

 

 

Install the Microsoft UAA bus driver before installing the sound card driver on models using HD sound cards and Modem. The driver is released in the form of a patch (KB888111) without being downloaded separately by Microsoft ), for a random genuine Windows system, you can directly download the patch through automatic updates. You can also install it on a random drive disc.

 

Take Lenovo desktop computer driver 4.1.6 as an example. The AD1986A sound card can be installed on the X: LX_SOUNDADIBusDrv409kb888111xpsp2.exe disc (remind users to pay attention to the operating system version, this directory also contains kb888111 patches for other versions of windows ). You can find the following Directory for the HD sound card of the C ++ SDK:

 

X: LX_SOUNDALC882MSHDQFEWin2K_XPuskb888111xpsp2.exe or X: LX_SOUNDALC882HMSHDQFEWin2K_XPuskb888111xpsp2.exe

 

After installing the corresponding patch, install the sound card driver and Modem driver correctly.

 

The attachment is the Microsoft UAA bus driver (KB88811). Download and decompress the driver and install it.
