Wave volume control keeps resetting to level lowest

Volume slider control wave reset automatically level the lowest volume.  Sometimes the cursor moves down, resulting no sound, sometimes the cursor remains stationary with no sound.  Still, I can click on the cursor and its takes a few moments and then turns off.  I checked my drivers and they are the most current available.  I am running Windows XP with SP 3.  Suggestions are appreciated.  Thank you.

I'm also facing this problem.  It is events actually very predictable.  It occurs approximately every 90 seconds.  VERY... WEIRD!

Through the "Process Monitor" sysinternals.com program, I traced the culprit to svchost.exe.  When this happens I see a 'RegSetValue"and is defined as follows:

HKLM\System\CurrentControlSet\Control\DeviceClasses\{6994AD04-93EF-11D0-A3CC-00A0C9223196}\##?#HDAUDIO#FUNC_01&VEN_111D&DEV_76D5&SUBSYS_1028040B&REV_1001#4&160BAD3A&0&0001#{6994ad04-93ef-11d0-a3cc-00a0c9223196}\#RearWave\Device Parameters\Mixer\ 2\Controls\ 0\Channel 0
Type: REG_DWORD, length: 4, given: 0

HKLM\System\CurrentControlSet\Control\DeviceClasses\{6994AD04-93EF-11D0-A3CC-00A0C9223196}\##?#HDAUDIO#FUNC_01&VEN_111D&DEV_76D5&SUBSYS_1028040B&REV_1001#4&160BAD3A&0&0001#{6994ad04-93ef-11d0-a3cc-00a0c9223196}\#RearWave\Device Parameters\Mixer\ 2\Controls\ 0\Channel 1
Type: REG_DWORD, length: 4, given: 0

(I guess "Channel 0" and "Channel 1" is ' left' / 'Right' respectively "").

If I change with Volume control program, 'data' that gets value are a value non-zero.  (Volume min = 0; Volume max = 65536)

When I check the 'stack' for this event, I see the following.  (This has been exported in a CSV file.  Should be visible in MS Excel):

'Frame', 'Module', 'Place', 'Address', 'path '.

Not really sure where to go from here, but it's very annoying! @!!

  • How can I get rid of the black bar that appears in the middle of the screen every time I have set the basic like the volume control features, or brightness levels?

    Hi, can someone help me with a really annoying (and I'm sure a simple to fix) problem?  I don't know if it's related to Windows 7 or if it's just my laptop plays up.  I recently upgraded to Windows 7 from Visa and whenever I have increase/decrease noise, brightness, etc (no matter if I do this using the key on the keyboard or via the control panel), a black bar appears in the middle of the display, indicating the levels that I'm reaching with the adjustments.  It's useful... except it does not disappear after that I'm done.  The bar stays there for all the time that I am connected and text blocks, images on the screen that I can't minimize or even move it out of the road.

    Hi Mkum

    The bar you describe look like this image?

    If so, this is part of the HP software that is installed on the computer.

    I have lost my Windows XP disc in a move and can't reinstall the file to a disk, how to fix this?

    When you use certain features sounds and Audio devices, you see a message like this:

    Windows cannot display the control of volume on the taskbar because the Volume control program has not been installed. To install it use Add/Remove programs in Control Panel.

    It seems that the c:\windows\system32\sndvol32.exe file is missing.

    This may occur if your antivirus/antimalware application thinks the file is suspicious and quarantines (effectively delete) the file.  You can replace the missing file with a backup copy of the file that is in another folder on your system.

    Describe your current antivirus and software anti malware situation: McAfee, Symantec, Norton, Spybot, AVG, Avira!, MSE, Panda, Trend Micro, CA, Defender, ZoneAlarm, PC Tools, Comodo, etc..

    Assuming that Windows is installed on your C drive...

    We know that XP keeps copies of critical system files in the following folder:

    c:\Windows\System32\dllcache

    Using the Explorer, search for or navigate to the following folder:

    c:\Windows\System32\dllcache

    Locate the sndvol32.exe file, right-click, choose copy (it copies the file to the Windows Clipboard).

    If your Solution Explorer settings are not set to display file extensions, you will see only a file called 'sndvol32' which has an icon that looks like to the volume control slider (this is the file you need).

    If the file is missing in the dllcache folder, look for a copy of the file in this folder:

    c:\windows\ServicePackFiles\i386

    Browsing from a level in the following folder:

    c:\Windows\System32

    Right-click on an empty area in the window of c:\windows\system32 and choose Paste to paste in the missing file where it belongs.

    Answered in the affirmative if invited to replace the existing file.

    Now try your features sounds and Audio devices.

    Note that run sfc/scannow will not replace the missing file because it is not this that sfc/scannow does.

  • Volume control turns itself higher

    I'm new to Vista.  Here's the problem: suddenly pops up a blue window with a counter of volume and the speaker and the computer volume caps.  If I open the volume control and move the slider to a lower level of the volume, the volume goes up.  Finally, the window disappears, but don't know where it comes from or how to eliminate it.  Nothing happens if I left-click or right-click on the blue window.  I'm not using a mouse, I use the touchpad.  It undergoes by contacting the touchpad?  Is this a virus?  I can't find all the controls for this and has never seen anything like this in XP.  It's incredibly boring, but I also understand that it may be something I do by mistake or due to a setting that may have to be modified.

    Brian-

    Thanks for your help.  I was following your instructions and try to isolate the problem.  So here's what happened.  My daughter has been using a Dell laptop, just like mine.  She had to lower its volume, while she hits an icon located above the keyboard and the blue window opens! It turns out that this is a feature on the Dell laptops.  There is a problem with it, but it's problem of Dell to resolve, not Microsoft.  The thing that amazes me, I called Dell for support and had to go through reset my computer to factory settings and tell him of this window was caused by a virus.  Thanks for the help, you helped me to understand, it's a matter of Dell.

    Hello

    The port microphone or line is not because you are looking for this audio * output parameters.
    The microphone is a device of entry so it s not who listed there.

    If you go into the volume settings > options > properties you can switch to HD Audio input.

  • FN keys and volume control does not not on Satellite A210-131

    Hello
    I have a Satellite A210-131 for 3 days now, and the FN keys do not work. The numeric keypad using FN works fine, just the F1-12 combined with FN do nothing. I have the latest drivers and utilities from the website...

    In addition, my touch volume control works quite stupid, it takes less than 20 seconds to set and then its way too hard... I always have to go to the sound control menu to change...
    Help, please!

    Hello

    It's very strange. Usually, if you press the FN key and keep down flash cards must be indicated at the top of the screen. Please try to restart flash cards: start > all programs > TOSHIBA > utilities > restart Flash Cards.

    I don't know what the problem with the touchpad and the control volume but friends Satellite X 200 (the same tablet like on your A200) works well. Problem described is quite strange, and to be honest, I don't know.
