Computer HP laptop sound does not work

Hello

I recently noticed a problem with my PC speakers does not. I'm not entirely sure which brings them to stop working, but if I remember correctly, the first time that I can remember what happens is after that I got my computer connected to the TV via an HDMI cable. Since then, the speakers seem to come and go. I think reboot my computer usually brings back them, but I was curious, if there is another way to fix other than that, and if I could do something to prevent this from happening in the future. Also, I'm interested to know why this is happening to my PC.

I have a HP ENVY dv6 Notebook PC

Thank you!

Hello

Try the following.

Open windows control panel, open Windows Update, select "View update history" in the left pane and then select "Installed updates" link in the next window.

Locate the KB2962407 update, right click and choose uninstall.  Once completed, restart the computer, open windows control panel, open Windows Update and select "Check for updates".  You will see the update that you have uninstalled just offered once again - right click and select "Hide update".

After that you may or may not need to remove and reload the sound driver - if you do, how to use Recovery Manager to reinstall the drivers and software is detailed in the document in question on the link below.

Recovery Manager - Windows 8.

Recovery Manager - Windows 7

Kind regards

  • Installed the Windows updates now sound does not work.

    I used the windows update Center yesterday and installed the updates that were for my computer, now my sound does not work. When I try and open "Dolby-Publisher of stars", I get this message:


    Any help tp fix it would be greatly appreciated as im am not very wise computer.

    Will,

    According to the scenario provided it seems that the problem is that you have updated the drivers for the audio device, but you have not updated the application (Dolby Home Theater - perhaps). If you have two choices, update the application to a version more recent or uninstall the installed update which is relevant to the audio driver (through programs and features - updated).

    See you soon.

  • Satellite L655 - sound does not work on the new install of Windows 7 Pro x 64

    Howdy all,

    I bought a Newegg L655-S5111, which was on sale, put an SSD, and then installed a legitimate copy of Windows 7 Professional 64 - bit, I got from my current employer (I'm a computer scientist). I've updated to the latest revision of the BIOS (1.70), and I have all the updates installed Windows, all drivers installed, including the correct drivers Conexant HD Audio and ATI HDMI Audio. Unfortunately, the sound does not work. Sound works briefly during my first install of Windows 7, then I cut it up until I could get it set up with a helmet. When I disabled it, she had stopped working.

    This laptop is less than 3 weeks at this point, old and I get no audio on headphones or speakers, even if Windows displays clearly no problems with the drivers, they have the latest version on a new installation, and I can see the audio mixer game. The laptop built-in microphone captures sound as well. I think that's probably not a matter of the physical interconnection, but more likely a software problem, I just have trouble identifying where it is.

    I have also no related error message than any where in the case of newspapers.

    Post edited by: ADMIN

    Can you please do a test and install original recovery image Toshiba, that you got with your laptop on this new SSD, just to see if it will work with the original image.

    Recovery image contains all the necessary drivers and OS is perfectly configured so each piece of hardware in your laptop should work correctly.

  • Internet and the sound does not work after uninstalling programs, System Restore also not work.

    I noticed that my computer felt a bit slow so I uninstalled a few programs that I knew were not very helpful so I restarted my laptop, and then the network and the sound does not work.

    I tried to use the system restore, but that does not work either and I tried to online solutions, but nothing works.

    Most often when a device does not work, it is because the driver is damaged. Re-install a new copy should help

  • Tecra M10 - Sound does not work on Windows XP SP3

    TECRA M10 sound does not work with Win XP SP3

    1. the drivers from the toshiba web site.
    2 chipset drivers and audio drivers were reinstalled no luck,.
    3. no mute FN + Esc
    4. feature eat that all drivers ok

    Hello

    If I understand your right all devices listed correctly in the Device Manager and you don t have yellow exclamation points?

    Normally, for high definition sound cards, you need two patches from Microsoft:
    KB835221 and KB888111.
    Normally, these patches are integrated into SP3 but it works only if you install the audio driver after SP3. So, if you have an older version of XP without SP3, you must update to SP3, all first and then install the display driver.

    So in your case, you must delete the current sound driver and restart the laptop. Then use CCleaner to clean the registry and system files. Reboot the laptop. Then download and install the driver of his newest Realtek Hompage.

    Good bye

  • Re: Sound does not work on Tecra M10

    Hi all

    I have a Tecra M10 with XP and all the drivers installed, but sound does not work.

    I checked the Device Manager and everything is fine, no red cross or whatever it is on the driver realtek audio.

    Everything on the sound properties. I even uninstalled and downloaded the audio driver from the toshiba site again but still no sound and no mistake.
    Can someone help out here?

    Thank you.

    Hello!

    The sound is turned off on your laptop? With the FN + ESC key combination you can enable/disable it.
    Check it!

    In addition to the high definition audio devices you need two patches from Microsoft to go looking for the proper functioning. Have you installed the two?
    Here are the links to the Microsoft Knowledge Base where you can download both:

    Hello

    If the sound does not appear on your laptop, you must first check the volume control on the side of the laptop. Turn it up to the max level.
    Then check the sound devices and audio in the control panel if any controller is disabled or turned to the lower floor.

    Additional connect headphones and check if you can hear something.

    By the way: have you installed the correct drivers? On the Toshiba page, you will find two different sets of portable Satellite L30
