HP Pavilion dv7-3190em problems with volume band and "base system device" in Device Manager

Hello

I just installed Win 7 (64-bit) and my volume control does not work properly. It does not turn the sound up and down, but the blue band is not displayed on the screen.

In addition, I seem to have a device or devices for which there is no drivers apparently. They are listed as "base system device" x 3 in Device Manager and "unknown device" x 1.

Thanks for any help.

Now, I just need to take care of the volume Strip.

Download and install:

MediaSmart SmartMenu here (version 3.1.2.2 for 32/64-bit Win7)

Before installing this software, that you must have installed at least a MediaSmart package software. The best choice will be in my opinion:

MediaSmart DVD here (version 4.1.4328 for 32/64-bit Win7)

If you do not use any additional software you can use another product that is:

3VRX here (version 2.5 for 32/64-bit Win7)

Note:

Here is YouTube video that shows what can be done with the 3VRX software.

  • Problem with the report and the system of axis 2d

    Hi, I'm trying to write a script with tiara, who wrote a 2d axis system in the report but I'm having a lot of problems with it.

    What I'm trying to do, is make 3 or more system axis 2d in the report, each displaying a part of the data of 2 channels (x = ch0, ch1 = y).

    With only 1 graphic I get what I want, but when I try to add the 2nd or the 3rd, they show without my defined x-scale and with the offset x different from the first chart.

    I tried everything, but I could not remedy

    I added as attachments the .csv file that I use to ch0 and ch1 and 2 screen shoots "what I get" (about the problem with the script) and "what I hope to get" (done manually, is what I'm trying to get the report)

    Hi lerman,.

    Here is an edited version of your code that works on my computer.  A problem that I know that I fixed it was that your presentation of the STATE was in the name-oriented mode but you use the variables based on the number to assign it X and Y channels.  The execution of these commands in a loop FOR makes it much easier to debug the code and to avoid any annoyance at first.

  • HP Pavilion dv7 6053er: problem with AMD graphics card.

    Hello. My name is Andriy. I use the HP Pavilion dv7 6053er of 2011 with win 7. I have updated my OS to win 10 in August 2015 and everything was good, but in September, I found a problem that I can't solve.

    As you know this laptop has two cards which ATI RADEON 6770 m video and its does not work. For example, in the Device Manager there are two cards:

    1 AMD Radeon HD 6700 M series

    2 Intel HD Graphics 3000

    In AMD Catalyst Control Center, I chose in the maximum capacity of all the options, but after I start, for example, Total War: Rome 2 the game see only Intel card. It is the same with windows I can't change the brightness using hotkeys (FN + F2 or F3). Keyboard shortcuts work because I can switch the WiFi, increase/decrease the volume and others.

    That's why I even reinstall AMD Catalyst Control Center, but it does not help.

    If someone knows how to fix this please help me.

    I have a solution:

    It was necesery to delet all software AMD and once mor reinstal AMD Catalyst Control Center after I did this all starts to work normally.

  • Pavilion H8-1205eo: Problem with 980 Ti and UEFI

    Hello! A few years ago I upgraded from the Radeon 7570 standard to use a 670 gtx graphics card in my H8-1205eo and everything went well. Recently I bought gtx 980 Ti to run the latest games at high heat. When I started the pc after installing the card, that it would not go beyond the blue HP screen and pressing ESC to enter the BIOS would show only a black screen with my characteristics listed. After reading a little online, I came to the conclusion that I need to change legacy to UEFI. I looked around a bit in the configuration menu, but wasn't able to find a way to change this in the UEFI. Should I buy a new motherboard, or I simply do not found the setting?

    Peter, welcome to the forum.

    You can't find UEFI because the computer is equipped with a standard BIOS.  HP didn't start using UEFI until mid-October 2012.  There is no way to upgrade to UEFI.  The last series of video card that did not use UEFI was 640 gt.

  • Satellite Pro C650D - problems with the audio and game controllers

    Hello

    I recently had problems with my microphone and speakers/headphones and game controllers.
    Sometimes the microphone stops working when on Skype, for example, but most of the time works fine, once again, when I restart the pc.

    Stakeholders sometimes still work when I connect headset.
    Some of the sounds are still coming through the speakers while some coming through the headphones.

    I have a usb game controller which also did not work everything properly.
    If I assign buttons in the program that they do not work in the game.

    All these devices are in Device Manager in a group that makes me think it's sort of annoying update doubtful that messes with them.

    Any body have similar problems or know what to do better?

    See you soon
    Laurin

    Hello

    Can you please send some details on the laptop model and the system you are using?

    With regard to the issue of sound/mic:
    > The microphone sometimes stops working when on Skype, for example, but most of the time works fine, once again, when I restart the pc.

    Are you talking about internal microphone or external? This only happens using Skype?
    In your case I would test the microphone using different applications to make sure that is not a Skype related issue.

    > Yet sometimes the speakers work when I connect headset.
    I recommend this thread:
    http://forums.computers.Toshiba-Europe.com/forums/thread.jspa?threadID=65295

    The user has had a similar problem, but this phenomenon was linked to the Realtek HD Audio Manager settings.
    She wrote:
    + In the upper right corner, there is a small yellow folder called "Connector settings" in my version. +
    + There, finally I could re-enable the setting "enable popup dialog box, when the unit is plugged. +

    + So now when I plug an external speaker or headphones, it appears, and I select the option "helmet" (instead of "line-in"), and then the sound only through the headphones/ext.speaker.+

    Regarding the game controller:
    > I have a usb game controller which also did not work everything properly.
    > If I attribute buttons in the program, they do not work in the game.
    I put t think its problem of laptop in my opinion, you must make sure that the controller is compatible with the games you play and also recommended to check some info provided by the manufacturer of the game controller.

  • How can I return to 6.3 4.0 I have never had a problem with 3.6 and now 4.0 crashes all the time tell me how to go back

    How can I return to 4.0 3.6 I've never had a problem with 3.6 and now 4.0 crashes all the time tell me how to go back

    Downgrade to Firefox 3.6 first of all uninstall Firefox 4, but do not select the option 'remove my Firefox personal data '. If you select this option, it will delete your bookmarks, passwords and other user data.

    Then you can install the latest version of Firefox 3.6 available to http://www.mozilla.com/en-US/firefox/all-older.html - it will automatically use your favorite courses, passwords etc.

    I recommend, to avoid possible problems with decommissioning, accessing your profile folder and delete the following files if they exist - extensions.cache, extensions.rdf, extensions.ini, extensions.sqlite and localstore.rdf. Delete these files will force Firefox to rebuild the list of installed extensions, check their compatibility and cancel the toolbar customizations.

  • Problems with wifi, bluetooth and gps in my iphone after updating iOS 6

    After that the last iOS 9.3 update my iphone 6 has problems with wifi, bluetooth and gps. Now, my wifi connection is slower and falls easily on a short distance. My bluetooth does the same. But the biggest problem is the GPS on my phone. I tried Island:

    -By doing a reset network

    -Do a reset total and restore my phone

    -To restart my phone twice.

    -Audit and third-party applications unnistalling

    Nothing works. I was in the apple store where they checked my phone and they say everything is ok with the phone. I'm not crazy, and I know when something does not work correctly. Also, I think it's iOS 9.3 update a reaponsible for my phone issues.

    Please fix bugs fast.

    Having the same exact problems since the upgrade. In addition, battery drains very quickly now, and sometimes the phone becomes very hot. It took to the Genius Bar and they told me everything was normal in the diagnostic tests. Restored, restarting, etc., and always the same problems. GPS locates me, but then don't follow my movement at all and told to go outside as the gps is not detected even if I am outside. Bluetooth connection to the car and watch grave intermittently. Signal WiFi is greatly reduced and falls easily.
