Sound does not work windows of the Envy 15 TS 8 and 8.1 of windows laptop

Hello

My audio Envy 15 TS (number of product C8P48AV) laptop has stopped working.

Since I got it, it happened 3 times.

Firstly was after 1 week of use. After a few days TI cams vice versa...

Then I upgraded to windows 8.1 and it stopped again...

Last night, a few days after the 2nd time, it started working again.

But today it stopped again.

I don't know how to solve.

On audion settins it is said that the sound works well.

If I'm on a call the microfone Skype works, but I can't hear anything.

I have not found it as the codec just to try to reinstall it.

Can anyone helpe me?

Kind regards

Hello Luiz,

Try the following.

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

http://ftp.HP.com/pub/SoftPaq/sp63501-64000/sp63555.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 allow this and then proceed to uninstall.

When you are finished, download and reinstall the Chipset driver at the following link.

Chipset Driver - Windows 8.1

Once the reinstallation is complete, turn off the laptop by pressing the SHIFT key when you click farm to temporarily prevent a hybrid boot.  One time finished, disconnect the power adapter, and then remove the battery.  Press and hold the Power button for 30 seconds.  Reinsert the battery and plug in the AC adapter.

Robinet tap away at the key esc that you start the computer to launch the Start Menu, and then select f10 to open the bios menu.  Press f5 to load the default values (sometimes it's f9, but the menu below indicates the correct key), use the arrow keys to select 'Yes' and press ENTER.  Press f10 to save the setting and still use the arrow keys to select 'Yes' and press on enter.

Allow Windows to fully - charge it will automatically load an audio driver, but let just this complete.  Then 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.

Kind regards

    My laptop has recently installed 20 or if Microsoft updates when I last reboot. Now, there not its coming out of the speakers or headphones even if the system indicates that it should work fine. It seems that some people have this problem as well and I see a possible solution for Windows 8. I, however, am running Windows 7.

    Thank you in advance.

    Check in the control panel-Sound-manage Audio devices.  My changed default "speakers, HP Wireless... ».  I have reset the value defaults to "speakers and headphones IDT high definition.  The sound comes back and everything is back to normal.

  • Sound does not work after updating the Audio driver on Satellite P100-248

    After an optional update to the audio driver in my Toshiba Satellite P100-248 conexant high definition, there's not more solid. I know it's the driver who caused the problem because it back to the windows generec driver and a reboot resolved the probem the first time around. Recently I had problems with my microphone so I was looking for a newer driver and installed upgrading the driver again by mistake.

    Now the noise disappeared again and I don't want to go back to the generic driver, but I can't find the conexant driver appropriate through Toshiba because the socket driver does not list my model. I tried a few of the drivers for the other models of the P series, but without success. Any ideas where I can find my driver? I'm on Vista 32 bit SP1.

    > but I can't find the conexant driver appropriate through Toshiba because the socket driver does not list my model.
    Hmm... Satellite P100-248 belongs to the PSPAGE series and this series of mobile is listed on the European Toshiba driver page sp I t really know what you're talking about.

    You will find also all the Vista drivers available on this page.
    I would say, download the audio driver and install it.

    Try all series.
    Fact is that some units of the Satellite P100 and Satego P100 series were delivered with the same features.

  • 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.

    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.

  • 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.

    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.

  • 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.

    Reset forced

     

    Specifications - power reset to solve Hardware and Software issues-Non-removable battery

    OR

    Laptops - power reset to solve hardware and software - removable battery

    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.

    Settings and the Audio System settings

     

    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.

    Computers laptops HP - laptop does not automatically loudspeakers when you unplug HDMI cable or device

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

    Laptops - no sound from speakers (Windows 8)

    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!
