Speakers not working not not on Satellite C640

I bought this c640 there is a little less than 5 months and it has worked perfectly until last week.
All of a sudden the internal speakers work not, but if I plug headphones they work fine. I looked at the drivers and everything seems very well and have the system restored to a wekk earlier and still no joy.

No idea what could be wrong?
I have not tried to re - start full to factory settings, which will be the last resort.

I saw on google that it happened to others as a powersave feature when the battery is low, but I used sector with no battery because I got it.

> All of a sudden the internal speakers work not, but if I plug headphones they work fine
This means that it is not driver problem because the headset works as expected.
The sound is also not cut because the helmet be too muted.

So, it could be a problem of speaker (hardware). But I think that it is unlikely
However, first of all I suggest you to check the settings in the control panel-> sound-> the Read tab

The speakers should be included here. Check that the speakers are set as default device and are enabled. In addition, you can view the properties.

If this doesn't help not the a recovery procedure must be done to check if it could be a hardware problem

  • USB speakers not working not

    I have a simple set of USB speakers (not only fed, no drivers) connected to my laptop (Vista, SP1). The Device Manager shows my Realtek sound card and my USB speakers. Control Panel > sounds > playback shows the two internal speakers and USB. I put the USB speakers as my default and configuration test reproduces very well, but only the internal speakers receive the audio stream. For some reason any, if I disable the USB speakers with their own switch, the internal speakers are leaving! I tried thses speakers on another laptop (Win XP) and they work fine. I tried several disconnected... rebooted USB ports... rebooted plugged... all this without success. Which setting I'm missing? Or is it another Vista problem? Help, please.

    my previous thread: http://xrl.in/2c49

    Thanks for your comments, Zack. After all my trials, I think things can go smoother by plugging directly on my laptop and avoiding the hub, but I think something else is happening... In any case, I discover this disconnection of the hub before you plug in the hub to the speakers (!). I'll live with it... Thanks again.

    Hi Tony,.

    Thanks for posting your query in Microsoft Community.

    I understand that you have a problem with the sound and I'll be happy to answer your query. I appreciate the efforts made in the patches that you tried. Let me ask you;

    • The question arises after upgrade to Windows 10?
    • Remember to make specific changes to the computer before the show?
    • What is the brand and model of the computer?

    Check the status of the device in Device Manager. The yellow exclamation point provides an indication of the current status of the device and could mean that there is a conflict of resources of system, a driver issue, or any number of other things.

    See the following steps to open the Device Manager.

    1. press the Windows key and X .

    2. click on Device Manager.

    3. spread sound, video and game controller.

    Also, try the suggestions in the article below:

  • Speakers not working do not and not even showing under reading devices in Windows 7

    Hey guys, I ask here as a last resort. I swear I tried everything to get my speakers to work.

    Here is my current problem:
    My new speakers (http://www.corsair.com/pc-computer-audio/pc-computer-speakers/gaming-audio-series-sp2500-high-power-2-1-pc-speaker-system.html/)
    does not work via my computer. I tried using MP3 players and my cell phone and they work very well on those, but for some reason, my integrated sound card refuses to recognize that I have even speakers.
    Here is a list of the things I've tried to address them:
    1. ensure that they are plugged into the correct port on the back
    2. ensure that they feed.
    3. I uninstalled and reinstalled my drivers realtek audio several times with restarting the computer without result.
    4. I even tried older drivers on the realtek Web page to see if they could work.
    5 I have even updated drivers for my motherboard itself to see if it could help somehow. with no luck as well.
    6. I tried a separate set of speakers (Logitech 5.1) and they don't work anymore. I confirmed these speakers worked on MP3 players and phones too.
    The only thing showing in my playback devices is: Realtek HDMI output, and he says it is plugged.
    Any Realtek Codec and the audio driver I tried loading, Realtek HD Audio Manager not show up on my computer.
    In Device Manager, I also tried to change the audio drivers manually, and I have been able to remedy.
    Here are some details of the computer.
    MS Windows 7 Home Premium
    64-bit SP1
    CPU AMD Phenom II X 6 1100t
    16 GB of Ram
    AMD Radeon HD 6900 Series
     
    If you need any further details to help solve this problem, please contact me as soon as you can and I'll help you!
    Thank you very much everyone, I really appreciate it.
