    I can sure use some help with this issue. I am running Windows XP SP3. I deleted “microsoft uaa bus driver for high definition” and successfully installed Realtek driver. I have sound!

    The problem (very annoying) has been every time I restart my system… upon startup Windows will inform me of new hardware found… (microsoft uaa bus driver for high definition) and wants me to install the drivers. Of course I don’t have them or if I do it will screwup the WORKING Realtek driver.

    How can I get rid of this annoying Hardware found message.

    Please Help.

    @SSStars :
    When the new hardware found window appears again, just click next and continue (automatically detect), windows should read “microsoft uaa bus driver for high definition audio” from realtek driver not from built-in windows driver.

    hope it helps

    voidzzz, thenks for help.

    I did as you suggested, that is “automatically detect”. Windows then displayed the following:

    I then backup to the prior step and clicked the the option that I will “tell” it were to find the drivers.

    Please wait while the wizzard install the software.

    The file ‘hdaudbus sys’ on windows driver cabinet is needed. Type the path where the file is located then click OK.

    I pointed it to c:\windows\system32\drivers… it found the file (hdaudbus sys) installed it and problem solved.

    Thanks so much for pointing me in the right direction.

    I’ve been dealing with this situation for weeks and can’t seem to find the most reliable solution.

    It’s seems that I’ve found the core problem. In the System Device in my Device Manager, the Microsoft UAA HD Audio Bus is not showing, so I can’t uninstall and re-install it. Do you have any idea why that happens? Thanks.

    @Andry,

    MS site explains how to remove UAA when it is not readily visible on your system.

    see “http://support.microsoft.com/kb/888111″

    The explaination is near the end of the article, but read the entire thing. This involves manually changing your registry so you need to back up your registry to be safe. The backup technique is referenced in the article.

    Good luck.
