hi guys

hope i am in the right section sorry if i am not

ok

after completing windows update i no longer have sound.

i have done the following already (courtsey of Navyjax2 from daniweb)



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/Fre...ry/remove11.zip (sorry i found the link to not work)

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.


I still have no sound
not sure if i have to add any reports to the post if any one has any further info please help

cheers

Hi kyliepak...

Have you tried rolling back to your original drivers?

You might also check that the Audio service is started and that the default sound settings are correct.

Click Start, then Run, and type services.msc...click "Ok". Scroll down the list to Windows Audio. Under "Status", is it Started?

____________________________________________________


Open Control Panel and double-click on the "Sounds and Audio Devices" icon. Under the "Sounds" tab, select "Windows default" in the Sounds Scheme drop down menu. Under the "Audio" tab, make sure that your Sound device is listed in the top two sections...if not, select it from the drop down menu. Under the "Voice" tab, make sure the Your Sound device is listed in both boxes...if not, select it. Under the "Volume" tab, put a tick in the box to "Place volume icon in the taskbar". Click "Apply" and then "Ok".

Now look down by the clock...is there a little speaker there? If yes, double-click on it and make sure there is not a tick in the box next to "Mute" and that the Volume sliders are all set to at least halfway.

Reboot

Sound?
