Keyboard sound control (volume) blocked to "Mute".

I've considered this some time between the post in the section on sound or hadeware, but now it is here in any case.

Well well, directly to the story, here's my problem: I use HP Pavilion DV4T-1400 (series of entertainment if I remember correctly). My sound (or volume) control pad was once very well. One day, after that I made a few changes on the software installed on my computer (I removed some) and restart it, I had a HUGE problem: the of sound control kept displaying "Mute" button (the Red speaker) no matter how many times I tried to touch and touch and touch...

The funny part is the bar of volume in Windows is still OK, and he has changed every time I touched the pad, for example from mute to turn the sound back on and then cut again for 3 keys. However, the volume key was just a "mute" red, and I can't hear any sound.

I read the support for the Pavilion DV4T-1400 on the home page, which describes the problem (or almost) even with mine. And he advises me update the BIOS by downloading the latest HP Support Assistant to "to" my computer. I did download and run twice, and all of a sudden, I noticed that in the process of "Tune up", it not there has no option "update of BIOS". All it is exactly the same as a regular disk cleaner option.

So I post this thread, hope someone can help me solve this problem. Three days without any noise is really terrible with someone who works in the field of design.

P.S. for a few days, I remember deleting some software with the kind of the name of "plugin" sound similar to, or do not remember the exact name.

Hello

The following assumes that you are using Windows 7.

Download and install the IDT Audio driver on the link below.

http://ftp.HP.com/pub/SoftPaq/sp45001-45500/sp45211.exe

Once the installation is complete, restart the computer and after Windows is fully recharged, check whether the mute button works now.

If she does still not work, download and reinstall the driver of buttons to quick launch on the link below.

http://ftp.HP.com/pub/SoftPaq/sp46501-47000/sp46731.exe

Again, once the installation is complete, restart the computer, let Windows fully load and check the button mute.

Kind regards

    missing volume control

    volume control was gone. I tried to go into my control panel to use it, but I get an error that says:

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

    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.

  • MMS 5650 sound control does not

    Hello

    The sound control to adjust the volume in my Center speaker does not work, it turn on and off the sound system, but the noise level is always the same, it has no effect on the sound level.

    I don't really know when the problem started, maybe when I installed Windows Vista, although I can't confirm that.

    I deleted and reinstalled the latest version of my card Creative sound, the SB Audigy 2 ZS (WDM).

    Any idea, comment or the link to the possible solution will be appreciated.

    Thank you.

    The only thing to check in the PC is the configuration of the speakers.  Go to Control Panel - hardware and sound - its Panel.  Left click on your speaker icon to highlight, and then click Configure and select the 5.1 speaker system.  You can also test the speakers on this Panel.

    If it is configured correctly, the problem is internal in the speaker system.  The only thing you can do is "resettlement" of all connections of speakers (unplug then plug into each connector by ensuring they are deep-set).  If it is not in warranty there is no repair for the speaker systems.  Even if you could find a place to fix the price of a new system of speaker would be about the same as the price of the minimum work.

  • Problem with the controls volume/internet on my laptop HP HDX 16

    Hey,.

    I have a laptop of HP HDX 16, around the age of 8 months. I keep having problems with the touch buttons that controls volume, bass/treble and the internet. The buttons randomly disappear by themselves, turn on and off Alternatively my volume/bass/treble from top to bottom and my internet.

    I have updated the drivers for the buttons to quick launch without result. I've also just updated my computer to Windows 7, so my Bios is brand new (the problem started before I updated to 7).

    As you can imagine, get my internet randomly stops and for the black volume screen blocking what I was doing and hang my computer is getting pretty annoying. Any help on this would be surprising.

    Thank you
    Printertron

    I also have the same problem. HDX 16, around the age of 3 months.

    I found to do all sorts of updates the driver, uninstall, System Restore (no), and does not help.

    I'm still on Vista, but when I get my kit to upgrade to Windows 7, I had planned to see if it resolved the problem.

    Technical support HP told me that if a recovery does not resolve the problem, it must be delivered to them, and the band of totality quicklaunch may have to be modified.

    I intend to make the recovery during the holiday season.

    Based on the fact that you got your computer 8 months ago, I assume that you have not used an upgrade kit. Which means, I would recommend doing a recovery before calling the technical support because they will just have to insist that you do anyway.

    An interim solution, when the volume control locks your screen is at the end of the process called "SmartMenu.exe". It will reload the next time that you start your computer.
