Sound Icon in control panel won't open - Windows 7


  • I am unable to open the Sound icon in my control panel. I have a Dell XPS computer ( 1 year old). Up until of late, I was unable to open ITunes but it strangely opened last night. I have run a check disk using the Windows 7 original installation disk without any luck. Strangely enough...after many weeks of the Sounbd Icon not was working for a few minutes last night but quickly failed when I started the computer this morning.

    I called the Dell technical support line and although most helpful....3 calls and 6 hours later....their only suggestion was to reinstall Windows 7 which I would prefer not to do for obvious reasons.

    Any help would be much appreciated.

  • Can you open it via command line?

    Start - Run - mmsys.cpl

    Should be located within C:\Windows\System32. I'd guess this could have prehaps been deleted or corrupted?

  • In addition to Reue's suggestion, run the  SFC   /SCANNOW    command. This will check and repair if necessary any critical Windows system files.

    Click on Start/All programs/Accessories  then
    Right click on Command Prompt option and select 'Run as administrator'.
    (or "Safe Mode" open a Command prompt)
    At the command prompt enter:  SFC  /SCANNOW

  • Hi Reue.

    I did as as you suggested and when I typed in the mmsys.cpl in the seach box nothing happened. I checked the C:|Windows\System32\ file folder and could not locate the mmsys.cpl file.

    Does this mean that this file has been deleted and if so, how do I reinstall this file?

    Thanks in advance.

  • Hi (and sorry for resurrecting an ancient thread),

      I have this same problem, I ran the SFC /SCANNOW as suggested above by JW Stuart, the results said that there were no problems with any of the files though.

    The problem started yesterday, I'd started up a game (Planetside 2) and was going to change my output device within the game (I have speakers connected to the onboard sound card, plus a USB headset).  I selected SPDIF for some reason (I was trying to find my headphones, but it turned out they weren't connected) and the game hung.  I killed the game, and since then, I haven't been able to open the Sound item from the Control Panel which is what I usually use to select my sound output device.

    Any ideas?
