Sound problems on computer, cannot change the sound settings

I had a long-standing problem in the audio settings of the Control Panel on Windows 7 where I can't change settings, configure anything or especially toggle of the devices. The options are there, but they have no effect when selected. Recently, I tried to connect my laptop to a TV, and as I could not set as the default audio device, I finally decided to try to fix things. I deleted and reinstalled the software Realtek my laptop and everything he has done is completely turn off my speakers, and all attempts to reactivate failed them. The unit displays in the control panel as a default active device, but claims of the taskbar that there are no speakers is connected, and if I click to set up the Realtek Audio, I have the same situation that before where absolutely nothing is happening.

I tried troubleshooting sound problems, and all I get is the statement that an audio device is disabled, no attempt to fix or any option to enable. Apart from a system restore, that in general, I try to avoid, I feel that I have tried everything I can think of to fix this and only managed to make it worse. No help available would be appreciated to receive my laptop back to a functioning State.

Model is a fickle Dell XPS L501X, if this is any help.

I tried both of these methods several times without success, but since I found a result to this problem online. (Here: http://www.techsupportforum.com/forums/f217/solved-no-sound-the-unsolvable-problem-take-the-challenge-594113.html)

I will stick also the solution here should someone stumbles on this page in the future trying to solve the same problem:

Hi, go to start search and type cmd search will return the click right on cmd.exe and select "run as Administrator" at the prompt, type: -.

net localgroup administrators / add networkservice
Press enter, and then type:
net localgroup administrators / add localservice
Press enter, and then type:
output
Press enter, and then restart your computer

Thanks for the help though, Yann!

    Why can't change the sharpness of safesearch under PC control change window

    Hi John,.

    1. What happens when you try to change the safesearch settings? You get the error message?
    2. Is research and results from Bing website suggestions option enabled? If this is not the case, turn it on and try to change the settings. This is because if the same is disabled, then the option in this window will be gray and you will not be able to make changes.

  • Satellite problem BIOS L750 - cannot change the boot sequence

    Hello reader/answering my questions.
    I am having trouble with my 750 ODN bios. This bios is an official update (3.6) from the center of support, and almost everything has been fine since (the plot thickens!). I decided one day I want to dual boot with linux, in particular Fedora (this is unrelated to this though).

    But, when I burned the disc and tried to direct (too test) boot the boot order has been on hard drive, first of all, I found! I rebooted and pressed f12 - did not work.
    I tried to delete and escape - neither worked. Then, I tried all the f keys - none of them worked.
    Whenever he took me to the Windows Start menu, and I explored it and I could not find anything.

    It is also important to mention that I'm under Win 7 SP1.
    I tried both PLoP and osloader (too boot from the dvd) - neither worked.
    I also do not remember what the button to start the bios was originally - Oops!

    Also toshiba with instructions logo never appears.
    I would really just change the order of boot however, the rest of the bios I don't need access too much right now.

    A separate issue is that Windows randomly decides he wants to check my hard drive, which takes forever, and he won't until he arrives to check it out. I think it may need medical help.

    But, no help, a qualified doctor or not, would be greatly appreciated.

    Thanks in advance
    Mitchell

    Hello

    > I also don't remember what the button to start the bios was originally - Oops!

    Pressing F2 by turning on the device could help you access the BIOS.
    But you do not need to change the boot order in the BIOS. You can do it by pressing F12. This should be done immediately after you have turned on the laptop.
    Then the start menu appears and you can choose the right boot device.

    1. are you able to click on the dropdown under screen saver?

    I have vista home premium and I can't change my wallpaper. I am logged on as administrator and can change most of the other settings, but a box tells be that the administrator has blocked the launching of the display settings control panel. I don't think that I have never done this, not intentionally at least. I tried to use the parameters of Environmental Variables, but it's like a foreign language to me - I don't know what to do with it. I don't have time for this! I have a job to do. Does anyone know an easy fix for this?

  • Cannot change the print settings

    I have a new printer, an Epson XP 430. My previous printer was also an Epson. With my old printer, when I chose to print (for a document, web page, etc.) the dialog always had an option to choose, black and white. I also could add to the presets and edit presets.

    With this printer, I can see the presets, but I can't make changes. When I click on view Presets, it is not an option for adding a new preset as it was with my old printer and remove and duplicate boxes are grayed out.

    I guess that this is due to the printer, not OS X, as I noticed the difference when I started using the new printer. Am I missing something somewhere? I rarely print in color, so I would have a preset that specifies black & white.

    Thank you.

    Sheri

    Since you have a new printer, you can create new presets. This is done through the printer with the selected printer dialog box, not through the page view Presets. When you select this option to print do the settings that you want to create a preset for and then click on the drop down preset menu. Select "Save current settings as preset" and enter a name for the new preset.

  • Cannot change the settings on the computer. No access to the administrator account

    Original title: I can't access permissions to change settings or programs.

    I can not access permissions to change any settings or programs and do not have access to an administrator account, I tried what allows one but you must have admin permission to do so. Please point me in the right direction, it seems that Ive tried everything. ID realyy don't want to spend money on software

    Hi Christophe,

    -With which user account you have connected? It is a standard user account?

    -What happens when you try to change the settings? You receive an error? In the affirmative, please let us know the exact error message.

    Since you are not able to create an administrator account, I suggest you to enable the built-in Administrator account.

    1. you must start the computer by using the Windows 7 installation media.

    Follow the steps in http://windows.microsoft.com/en-us/windows/what-are-system-recovery-options#what-are-system-recovery-options=windows-7 to enter the recovery options in Windows 7.

    Note: See the manual of the computer to change the Boot order in the BIOS and set the CD/DVD as first boot device.

    2. Once you start the computer by using the Windows 7 installation disc, follow the instructions on the screen then go food Advanced Options and select command prompt.

    In the command prompt, type net user administrator / Active: Yes

    After the command finishes, restart the computer and then log on to the administrator account by default, change the account type of the old user account and make as administrator and check if you are able to change the settings.

    Follow the steps in the http://windows.microsoft.com/en-in/windows7/change-a-users-account-type to change the account type of the user account.

    Once you have set the administrator type account with your user account, disable the default user account by following these steps.

    1. login to your user account.

    2. open the command prompt, type cmd. exe in the run search and right click on cmd.exe and select Run as Administrator.

    3. type net user administrator / active: No.

    This will disable the built-in Administrator account.

    Hope this information is useful.
