I'm running XP Pro SP3 on Intel P4 Board (D915PBL) and I have a Realtek Audio Driver 5.10.0.5605.

I have a WIRED network which utilizes a Linksys Wireless-G Music Bridge.

On boot up, I get the message "RunDll32.exe unable to locate component" "This application has failed to start. UserData.dll was not found. Reinstalling the application may fix this problem."

RUNDLL "Error loading cmcnfgw.cpl. The specified module could not be found."

My main problem is that I can't find any information on this cmcnfgw.cpl and no one seems to know what it is or what application it belongs to. I am assuming that this file has something to do with my sound card or a sound driver left over from some uninstalled program but don't know, or it is in someway related to the Music Bridge (CmFlywav.exe)

System Config Start Up Tab reads:

RunDll32 cmcnfgw.......RunDll32 cmcnfgw.cpl, CMICtrlWnd..............HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

Does anyone know what this file is? :thumbsup:

No system manufacturer. I built it myself.
I've been to that google page before.
I have updated/modified original post as well.

I believe the 3d link of the Google link...tells you what the file (normally) is.

Louis,
I've seen that page before, but I didn't understand until I did a search on "CmiCnfg Dynamic Link Library" and came up with this, although it doesn't specifically name the error I experienced, it does appear to be the solution, even though I don't believe I've ever seen this program on my system. It maybe some leftovers from a recent formatting.



Background: This error occurs after trying to uninstall the updated (and overrated) C-Media WDM Audio Driver for onboard sound that appears after upgrading to XP SP2 and/or going to WindowsUpdate. Likely the driver didn't work, so you tried uninstalling the driver and were going to put back the old Realtek AC'97 driver, but couldn't get rid of the updated driver.

To fix: Start, Run, type in "regedit" (no quotes), and delete the cmaudio string from
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run. This makes it so it will not run on startup and try to find the cpl file that was deleted during the uninstall or not installed correctly by the installer in the first place, whichever your case depending on when you started seeing the error. If your sound was working perfectly before this, you are done. To get your sound working again if it isn't, read on -

While still in the registry editor, click on the top computer icon in the Registry Editor to highlight it (so that it will do a complete search of the registry and not just from your present point forward), do a Find (Ctrl+F) and find and delete all KEYS related to cmaudio and C-Media, not just the string entries, but the KEYS, except for that entry in the Run key I mentioned above, just delete the cmaudio string for that one.

Delete the string "CMCPlus" from HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Control Panel\Cpls to get rid of the Control Panel icon, and delete the file it points to that resides in C:\Windows\System32.

Download this remove utility from

http://ekiis.com/Freesoft/binary/remove11.zip

and run the file you find in the zip file - it can be ran without extracting it from the zip. Take out the C-Media Audio Driver line.

-- NOTE: This utility is for taking the name out of the Add/Remove Programs section only, and does not remove it from your computer, but it is very useful for issues like this when we are MANUALLY uninstalling a program to take it out of the Programs list and should work in 98/ME/2000/XP.

Delete these files from the C:\Windows\System32 directory (or "System" directory for Win98)

cmirmdrv.exe
cmirmdrv.dll
cmuda.dll

Delete everything you can readily delete in C:\Temp, C:\WINDOWS\prefetch (XP only), C:\WINDOWS\Temp, and C:\Documents and Settings\%YourName%\Local Settings\Temp (2000 and XP only), so that there will not be any files left for it to try to recover the driver from. You will likely have to leave things that start with hsperfdata_ and Perflib_Perfdata_***.dat files if you find them, but should be able to delete most others without changing attributes.

Now open the Device Manager (Right-click "My Computer", hit "Manage", then find Device Manager in the Computer Management console). Right-click the C-Media WDM driver under Sound, video, and game controllers, hit Uninstall. Then right-click the top computer icon listed there with your hostname beside it, hit "Scan for hardware changes". It should install a generic "Multimedia Audio Controller" instead of the "C-Media WDM Audio Driver", though you might see that C-Media Audio for just an instant before it reverts back to a generic driver (if it stays, you'll have to go back through the registry again, delete the system files again, and do a full search of your hard drive for those files so they don't get re-copied again). From here you can download your specific Realtek AC'97 Audio Driver setup.exe file here or use your motherboard's installation CD to re-install and you should have sound again.

No problem :thumbsup:.

It's always good to remember that many fixes (if not all) on a PC...is just trial-and-error. If one thing doesn't work, there's always something else to try.

UPDATE:

I finally found out where the C-Media software came from. It seems it is installed along with the software for the Linksys WMB54G (Wireless/Wired Music Brige). There is no direct indication of it's existance through the WMB's driver interface, but it's in there. Apparently, it is not a very critical part of the application (may be supplemental or redundant ot other PC drivers) because I deleted all instances from the registry and the bridge works just as it always did. At any rate, the mystery is solved.
