Cannot Find Microsoft UAA Bus Driver for High Definition Audio (hdaudbus.sys)

Submitted by Kevin Kleinfelter on Mon, 11/16/2009 - 21:26

Awhile back, Windows XP started doing the hardware auto-detect thing for no reason I could discern, and it reported it couldn't find "Microsoft UAA Bus Driver for High Definition Audio".

So I Googled around and found pointers to http://support.microsoft.com/kb/888111, but that turns out to be a really old hot-fix and it wouldn't install on my XP-SP3 because the patch was created before SP3.

However, there was an easier solution.  I searched C:\Windows for file names containing "hdaud" and found it in both C:\WINDOWS\ServicePackFiles\i386 and C:\WINDOWS\system32\drivers, so I just filled-in C:\WINDOWS\system32\drivers in the where-do-I-look-now field, and Windows accepted it.

Your solution WORKED for me!   I pointed the install wizard to c:\windows\servicepackfiles and voila there it was! 
Which of course begs the question "why couldn't the Windows "wizard" find it" ?!?!?!?
Thanks again!

Thanks a lot! This took me about 30 seconds to find and finish my install. It saved at least 30 minutes and probably more like 30 days if I would have pursued my hotfix request through microsoft.

The Microsoft patch is not for Windows SP3.  This way works.  Thanks a lot!!
