HD Audio Device Cannot be Detected in WinXP SP3 RRS feed

  • Question

  • Hi,

    I purchased WinXP Home Edition for my new PC. The SP3 including edition was supplied by OEM.
    The ASUS P5QC motherboard includes Realtek ALC1200 High Definition Audio CODEC. But Windows does not detect an audio controller and no audio service is available. The Realtek driver installation finishes without errors, but ASUS all drivers installing program still shows it as not installed.

    In forums I fuond that KB888111 is lacking to support HD Audio devices and required the patch KB888111. This patch exists only for SP1/SP2, but not for SP3. I cannot uninstall SP3, because Windows was installed already as SP3.

    I found a solution in how to install KB888111 on top of SP3. But I cannot implement this solution because there is no Unknown PCI Device among hardware to implement proposed solution.

    hdaudbus.sys exists inWINDOWS\system32\driivers, but hdaudio.sys is absent. So it looks like UAA Bus HD audio driver is either absent or incomplete and this is probably a reason why Windows cannot detect exising controller.

    Any solution/suggestion to make my audio system work will be appreciated,

  • This has been an ongoing problem with "partial" UAA HD Audio support in Windows XP SP3 since SP3 does NOT include "generic" UAA HD audio drivers.  SP3 only includes the HD Audio Bus driver (hdaudbus.sys) file but NOT the audio drivers (hdaudio.sys, hdaprop.dll, hdashcut.exe & hdaudres.dll) from KB888111.

    Check out the following sites on getting the Microsoft UAA HD Audio drivers to install and work under WinXP SP3:

    Hope this helps your situation with the UAA HD audio drivers.
