The volume control has mind of its own

I have a HP1428 DV7 ca, Win 7 Home Prem 64 bit running. Recently my volume control seems to have achieved a clean mind. At first I thought it was related to HP MediaSmart, so I removed it. It stopped at the volume control bar to constantly and irregularly flashing on the screen. However, when I open the mixing table under windows I see that it is always very strange, the volume increases in fits and starts. None of the volume controls at the top of the keyboard do not work. The MediaSmart button stays on and the mute button is not the drawer of the volume control does not work either. I thought that removing MediaSmart and put it back in place, it should correct the problem, he didn't.

Thank you.

Hello

It may be a hardware problem with the band capacitive itself, but about the audio, try the following.

Download IDT Audio Installer on the link below and save it in your downloads folder.

http://ftp.HP.com/pub/SoftPaq/sp45001-45500/sp45073.exe

One time finished, open windows control panel, open Device Manager and open sound, video and game controllers.  Right click on the IDT device and select uninstall - also, you should get a command prompt to delete the current driver, check the box to enable this and then proceed to uninstall.

When finished, restart the computer and let Windows load completely.  Open your download folder, right-click on the IDT Installer and select "Run as Administrator" to launch the installation.  Once this done, do a right-click the speaker icon in the taskbar and select playback devices.  'Speakers and headphones' left click once to highlight, and then click the Set Default button - check if you now audio.

The MediaSmart you make reference to the application's HP MediaSmart SmartMenu, which can be downloaded and installed from the link below - you must have at least a MediaSmart application installed before installing SmartMenu.

HP MediaSmart SmartMenu.

    PS CC 2014.1.0

    Windows 8.1

    24 GB RAM

    Dual GTX 560ti last Nvidia.com provided pilots

    Since the upgrade, I had what I thought was about the Clone Stamp tool, but in fact, it's a matter of brush (just Clone Stamp using a brush, of course).

    See attachment. Only, I drew the short vertical part goes to the top. Once I have let the mouse, big leg to leave around 10:00? Well, it is with the permission of Adobe, I suppose.

    I also have the same version on a Yoga Pro 2 - and it does not, however, if the brush strokes are too fast, the brush back to the place where it began, draw a line back to the source.

    Fun stuff.

    I "solved" it by getting a new video card - a GTX 980. I have two 560's, and two had the issue on different PCs. I think it's a problem with Photoshop and the GTX 560 or line 500. I realized that Adobe was not going to do anything because they get my monthly payment without worrying.

    Hello Kluggerjo,

    Thank you for reaching out to the Community Support from Apple. I know how important it must be able to count on your devices work as expected, and I have a few steps that should help resolve the behaviors you see.

    I would recommend to go by resetting your management system (SCM) controller. MSC helps control and regulate different material on your Mac, including Bluetooth systems.  This article will guide you in this process: reset the management system (SCM) controller on your Mac.

    If you still experience the issue after the test, you can test the behavior to a test user. This will help us to determine if the problem is systemic or isolated to your user account. This article will guide you in this process: How to test a question in another account on your Mac user

    If the behavior is duplicated to the test user, I'd recommend reinstalling El Capitan. This will not delete your data. To reinstall using the recovery mode, take a look at this article: How to reinstall OS X

    If you experience any problems or have any questions, please let us know. The entire community is here to help.

  • The volume control on the right side of the bottom bar has disappeared.

    Recently, I was a watch UTube and the sound was too loud. When I went to use the volume control which has always been on the side of the
    the bar lower, it was gone. It could have happened after an automatic update of Windows. The same thing happened on one of my friend
    computers. I am running Vista on a Gateway laptop, but my friend has Windows 7 which should not be the problem. How can I reduce the amount if I can't find the icon and there is its control on the video or for that matter the music I listen to on the Web?

    Right-click on the taskbar, click Properties, notification area and uncheck and then click on the volume control on the bottom.

  • Windows has a mind of its own?

    A few weeks before that I demoted Win.8.1 of Win8. I can't support either.

    Tonight, I get a message that my computer needs to reboot for Win.8.1 can complete loading.

    I never said I wanted to move to 8.1. Windows has a mind of its own

    and upgrades to the next version without worrying about whether you want it or not?

    Well, I guess I'm stuck with 8.1.

    This happened to someone else?
    Bob

    It apparently * a * is happened to others, even though I have yet to see it happen first-hand (or with anyone I help/manage personally who chose to not move to 8.1 for a reason any.)

    If most of the 8/8.1 aversion is the interface - 8.1 is the best choice because it gives more options to customize without know entirely too much about the inner workings.

    If you don't mind a suggestion - check out the first post in this discussion to see if some of the suggested changes would help you with your discomfort with Windows 8.1 or not...

    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.

  • The volume control on the Satellite Pro A200 with Ubuntu 7.10

    I have a Satellite Pro A200GE-1F9, I did recently to dual boot with Vista and Ubuntu 7.10. It's the first time I used Linux and most things are going well so far.

    However, the volume control (a wheel at the front of the laptop) does not control the volume correctly with Ubuntu, rather than increase the volume smoothly as with Vista, it increases in a 1/8 of maximum volume jumps, the on-screen volume control is always smooth. I think that it is at least partly due to the change of a material volume wheel, as with the latest Toshiba, I have used, for a version of software based. It controls the system volume and runs continuously, without stop at maximum or minimum volumes.

    Does anyone know how to change this change in volume for a smooth jump?

    Thanks for any help

    Hello

    given that no one here has no idea, nor pilots, nor any information about the driver from toshiba support, nobody will be able to give you some useful information.

    Have you ever google and checked the ubuntu forums? According to me, which will bring you closer the source here instead.
    So just to start to ask in the ubuntu forums because I think that someone is there who maybe has the same problem as you.

    I hope that artistry a kind of programmer. ;)
