How To Fix The Cmicnfg.Cpl Error

Step 1 – Remove The Registry Settings For Cmicngf.Cpl

Editing the registry is complicated and these steps have been made so that you can follow them as easily and as safely as possible:

  • Click Start, select Run.
  • In the box type ‘Regedit‘ (without quotations).
  • Click OK.
  • This will open up the Registry window.
  • Once in the Registry window, navigate to the following key.
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run.
  • Once you have done that, delete the cmaudio string.

Deleting this string will in turn, stop the error code from appearing at system startup, although it seems that we have successfully removed the problem, we haven’t. We have only just removed the command that causes the error to appear at system startup, not the actual problem itself.

  • In the Registry window press Edit, then select Find.
  • Once you have done that, search for all the keys that are related to cmaudio and C-Media, and delete them from the Registry.
  • Navigate your way to the next registry key:
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Control Panel\Cpls
  • For this key you need to delete the Cmcpls string, this will delete the WDM Audio Drivers Control Panel icon.

It is highly recommended that you create a backup of the registry just in case you make a mistake and you need to go back.

After you’ve cleaned out registry keys left by CMedia, you then need to delete the files it may have left on your PC as well. To do this follow these steps:

  • Delete the following files:
  • cmirmdrv.exe
  • cmirmdrv.dll
  • cmuda.dll
  • cmicnfg.cpl
  • C:\WINDOWS\System32\Drivers\cmuda.dll
  • C:\WINDOWS\System32\LastGood\cmicnfg.cpl
  • You need to also delete any related file that are located in these folders:
  • C:\Temp
  • C:\Windows\Temp
  • C:\Documents and Settings\%UserName%Local Settings\Temp (Windows 2000 and XP only!)
  • C:\Windows\prefetch (Windows XP only!)

Step 3 – Reinstall The Original C-Media Drivers

  • Open the Control Panel.
  • Select Performance and Maintenance.
  • Select System.

Tto do this you need to right-click on the top icon and select the Scan for hardware changes. This process will search your entire computer for any Plug and Play devices, this process should seek out your Sound Card and should also install the generic Multimedia Audio Controller and not the C-Media WDM Audio Driver.
