Anyway just follow this guide:

http://www.tymes.net/swenum/fix-swenum1.htm

In the first step open a Command Prompt via start > All Programs > Accessories > Command Prompt

Then copy these lines:

Code:

md \temp


find /V "ExcludeFromSelect" %systemroot%\inf\machine.inf>"\temp\allmachine.inf"


copy /y %windir%\system32\drivers\swenum.sys \temp
copy /y %windir%\system32\streamci.dll \temp


rundll32.exe shell32.dll,Control_RunDLL hdwwiz.cpl,,1

Then with your cursor on the command prompt right click. That will paste the commands and open the Hardware wizard.

The above tutorial is pretty self-explanatory after that.

At the end of the process the yellow! should be gone then you can reinstall the audio drivers we found earlier.
