Sound does not work on my dv7 HP ENVY relatively new

In the last two weeks, the sound stop working on my laptop.  Since the purchase, I was able to cut the sound and turn it back on without any problems, but now when I turn the sound back on nothing happens.  The sound icon and the Volume mixer all show that the sound works and is set at the highest volume, but nothing comes out.  Given that this laptop has beatsaudio, it's frustrating.

Hello

Tangles and "be stuck."

 

The sound can be set on come others as you wish - sometimes parameters do not recover as expected when devices are added or removed.

 

If the settings Audio (sound) are OK, but the system is just confused, confused, or "stuck in a loop" on what is happening with the Sound System, then you could get away with just do a power Reset.  A power reset is nothing more drain away from the stored instructions that the computer uses restart to restart and forcing the system all over again and get new instructions from the operating system of the computer.   Feed the work of reset for a bunch of weird stuff that confused laptops and makes them act weird - it works for that?  Meh.  Perhaps.  Quick and easy to make.  It will not change the data on your computer.  You decide.  You are the admin.

Power reset cannot tell the difference between drivers - it does not analyze a driver before applying.

EXAMPLE:

If the driver on the disk is the wrong driver before rebooting, it's always the wrong driver after the reset.

If the INSTRUCTIONS of the driver are tangled, messed up, missing or damaged, then the reset may solve the problem.

 

 

Why a power reset works to solve some problems:

The Hard Reset Power does not install anything on your computer, it does not remove anything from your computer, and delivery to zero do not change or update the programs on your computer.  Your data and files remain as they were before the reset has been applied.

Why a power reset does not work:

If the problem is more than a simple tangle, if 'good job' on the computer is not enough - in other words, if you need an update, a new driver, or if there is a problem that can not be "unraveled", then the reset does not work.

If there is a hardware problem power reset will not work.

More specifically, with the addition / removal of a monitor cable HDMI / TV, the value default sound can remained on the monitor / TV after the device has been removed.

Here is a document that covers "All things Sound" and can help you double check the rest of the sound system:

Recovery driver

If the installation is really messed, it may resort to reinstall the Audio driver.  Because you have only your system for a short time, you can probably use the Audio driver in your recovery manager and without having to go out and download it from website to your computer.

Using Recovery Manager to restore the software and drivers (Windows 8)

Good luck!

  • 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.

  • 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:

    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.

  • 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.

  • Sometimes sound does not work on Satellite A65

    I got my pc for years and never had this problem until recently.
    Most of the time the sound does not work, but sometimes when I restart (and sometimes when I'm warming up stand-by) the sound will return.

    When it works it lasts as long as the PC is on, but it the PC itself will be down due to overheating sometimes, and even if it does not, I do not leave all the time.

    When the sound does not work I can not play with the exception of windows media videos.
    Any youtube or videos of the similar site will only play for about two seconds and then pause, no noise at all.
    Same thing for my iTunes.

    When the sound does not work I can play iTunes all night, but when it isn't the songs does not play again. The cursor remains just at 0:00.

    Is there something I can do?

    Hello

    As a first step, the fact is that this laptop is pretty old. I think around 4 years. Am I right about that? There may be a lot of dust on the inside and as a result you have it sometimes overheat issue. May be time to clean the laptop.

    If is also possible through these overheating problems is something faulty now. It may be that some contacts (associated sounds) are not much more and the contact is it sporadically. To be honest, to me that sounds like hardware related issue. I really don't think you can do much alone. Maybe try to make clean OS install and see what happens. If the problem persists or you have to get an external solution or takes it to the authorized service provider.

    Hello:

    Then I recommend that you follow the instructions in the guide to the link I posted above.

    After you install the MS UAA driver, you may need to install the audio driver updated the posted on this link:

    Conexant High Definition SmartAudio 221 drivers (ModelC700, Vx5xx series and dvx5xx and ABOVE )

    Pilot modded by silver here

    Unzip it to a folder... Use the device, right click "Audio Device on HD" Manager, choose Update driver,
    Not to connect, install from a list or specific location,
    Select don't search, I will choose the driver to install.
    For the hardware Type select 'show all devices '.
    Remove control "Show compatible hardware" and click on 'disk '.
    Next... Navigate to the unzipped folder and choose the "WiSVHe5.inf".
    Ignore XP when he complains, Reboot.

    If none of this works, try to reinstall XP and start from scratch. If you do not see your appliance an audio controller if you reinstall XP, then more than likely it is a hardware failure of the audio chip.
