Sound goes silent in Win7

My sound shuts in Win7 - completely, both locally than on the net.  I can get it back with a cold start again.  Two questions: why?  Is there an easier way to get back on that goes through a cold start?  Because it is new with cold start, I think we can eliminate the problems of connection type.  I tried a program of solving problems and it could not find the speakers!  I think that it is a program that sends a signal that is 'off '.  But which?  And how to fix it?

Thank you.

  • Tabs glitching, videos goes silent

    Sometimes when I close a tab, the next he tab changes will be glitch out and have a few artifacts from the site I was immediately. For example, I have a tab on Google.com and a video on Youtube in another. If I close the youtube video and go to the tab of google, the youtube tab items will appear on the tab of google.

    Regarding the videos goes silent, it mainly youtube. When I watch a video and you want to skip ahead, the video will act as if it was the break. The pause button will change to the symbol of the room instead, but will not change to pause when I click it. The video will continue to play and the audio will be completely muted. So far, the only way to fix it was to close and reopen the tab. So far, it happens mostly when I go full screen.

    I'll try to get a picture of the first problem, but the second problem is so random, I'm afraid that I won't be able to get something to show.

    The seeds just started recently? 33 Firefox introduced a new feature called 'off hand Thread Compositing"(OMTC). There is a preference to turn this off if you want to try it. You will need to exit and start Firefox again after the change is made.

    (1) in a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.

    (2) in the search above the list box, type or paste the layer and take a break while the list is filtered

    (3) double-click the preference layers.offmainthreadcomposition.enabled from true to false.

    Any difference?

    On the YouTube videos, they play in the Flash player or built-in to Firefox HTML5 Player plugin? Usually you can distinguish by the context menu for the player: plugin Adobe has a distinctive context menu short instead standard menu shortcut of Firefox.

  • Sound goes off when a game is open.

    Any time I open World of Warcraft or League of Legends, the sound goes out on my Presario F700 Compaq. IF I have music or ventrillo running in the background that goes out. I spoke with another player of World of Warcraft and they have the same problems and we all run Windows Vista. After that I have to restart or restart the sound works fine, but at any time if I open these programs simply sound cuts and forces me to restart. Any ideas? And yes I updated my sound cards and other from the website of the manufacturer.

    Hello

    Make sure you have the latest drivers, but I suspect that these are questions that need to be
    addressed by the authors of the game so I would check with their respective support options.

  • The President goes silent. No control on her.

    I usually run with sound muted, while using the 'secret' just turns off its own and the volume knob goes up on its own. A blue rectangle with a speaker icon at the end sometimes appears as well.

    Hi carol129,

    1. did you of recent changes on the computer?

    2. where do you find a blue rectangle with a "speaker" icon?

    3. when the question does not start after the start?

    Method 1

    I suggest that you perform the clean boot procedure to check whether a third-party program installed on the computer is causing the problem.

    To help resolve the error and other messages, you can start Windows Vista or Windows 7 by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

    See the link below to learn more about how to clean boot.

  • Email notification sound goes back to default

    Three times now, I put my email notification sound for Facebook pop. It works for awhile but then goes back to "Droid". Do not know why.

    Anyone? 2.2.1 running and have noticed that since the recent update.

    Daringo wrote:Three times now I have set my email notification sound to Facebook Pop. It works for awhile but then goes back to "Droid". Not sure why.Anybody? Running 2.2.1 and have only noticed this since the recent update.
    

    I don't know why this is happening, but I have a possible workaround.  I do not use facebook on my phone, so it's just all the thoughts in my head.

    First of all, where is the sound of facebook that you use?  I think this is the facebook app doesn't like to share her sounds with other applications or the phone.  What happens if you were to copy the sound where it is now and put it in your notifications folder and set it as your notification from there.  I don't know if it will work, but it's something to try anyway.  I hope this helps.

  • After a pause of a flash-based video it goes silent.

    I have problems with no sound when you play videos in Firefox flash-based.
    It affects all YouTube, Vimeo, Dailymotion and other sites as well.

    It happens:

    • When ads are displayed.
    • When I click on "pause" and then resume, sound disappears.

    To get her back, it helps to refresh the entire page or to start the download from the beginning.

    One funny thing is that it works in IE and Chrome, so I don't think it is in any case related to the Flash Plugin itself.
    The same thing happens to me at work and when I'm at home, I doubt videos Flash would be blocked by politics of the business anyway, because a lot of meetings etc. are published also on YouTube.

    Question began already some time ago, I tried to reinstall FF and all the Adobe software, including Air and Flash, but so far without success.

    I looked through a lot of bandages and forums to sort and still the same.
    Anyone with similar problems there?

    If you need more details, feel free to ask. Any help or advice really appreciated.

    It is must have been something wrong with my operating system, with the specific user account permissions.
    More happens if another user is connected.

    If a lot, you have problems with you audio just follow these steps:

    Follow these steps:

    (1) press on [Windows] + [X] on your keyboard and go to Device Manager

    (2) go to the sound, video and game controllers

    3) click IDT High Definition Audio CODEC

    4) click on the driver tab

    5) click put updated driver

    (6) select Browse my computer for driver software

    (7) select Let me pick from a list of device driver on my computer

    (8) select it Audio device high definition

    (9) to read the warning and click Yes if you understand the risk

    (10) restart the computer

    When your computer restarts:

    1) click on the Control of the Volume (speaker) in the bottom right of the taskbar.

    2) click on speakers

    3) click on the enhancements tab

    (4) If you do not know a lot about audio and to help prevent speakers, earphones, ear lesions, click the Equalization of the volume and click settings, and then move the slider to 3/5-4/5 in the direction of Long, then click OK and apply

    5) enjoy its AWESOME.

    BE CAREFUL, the sound of unlocked chip IDT is VERY STRONG, and based on my experience in audio engineering, I wouldn't recommend listening to it more 45% volume without the Equalization of the volume turned on.  I'm listening to a modern CD and without the limiter and compressor, 50% by volume, border level EAR ENDOMMAGEANT level on my helmet.  Also, without the pre-installed, limiter high volume CAN DAMAGE YOUR SPEAKERS.

    A little bit of my solution:

    This solution essentially replaces the IDT pilot with a Microsoft driver.  If you damage your laptop using, your warranty may does not cover repairs, so please, please, please use the limiter or prudent.  On the same note, don't damage you either; hearing loss is very difficult to self-diagnose, because you lose hearing gradually by the loss of sensitivity to higher frequencies.  It is not 'feel' special, just somehow, you notice that you stopped to hear the singing of the birds and leaves rustling a day, in order not to blow your music.

    Finally, I'll probably revisit this solution some time, as I prefer to use the IDT pilot and have my EQ work.  This is possible through the IDT folder in Program Files and hacking essentially parameter files in a text editor, but it is rather tedious and complicated.

  • My iPhone screen 6 is black but the phone still works as the sound goes in and out. I can't restart and have tried several times and cannot reset on iTunes because need to unlock my phone.

    Thank you for using communities of Apple Support.

    I see that you get a black on your iPhone screen, even if it is enabled. I would recommend that you take a look at the following article:

  • Satellite A30 - 614L: Sound goes wrong and stops completely

    After some time using laptop computer, his first goes wrong on and outside and after awhile stops completely. When it really starts to go wrong is quite unpredictable.

    Sometimes after 10 min, but also sometimes after hours. I have tried to re - install the driver the most recent, but which did not help. When the noise was gone, the only cure is a reboot.

  • Latitude E6420 Sound going headphones instead of speakers

    I'm on a Dell Latitude E6420, and I'm having a problem with my speakers.

    What I have found is that by default, the computer sends sound for headphones, regardless of whether or not they are connected. There are two audio devices in the control panel > Sound, one called speakers/headphones and the other called Communications helmet.
    According to me, that both failed to the headphone, because when you play the normal sounds, they come through the headphones, and when you run the function 'Test' for the Communications headset, that comes through the headset as well. However, when you use the Test a helmet of communication and when you fill out a change in the volume of Communications helmet, the normal sounds (those who play with speakers/headphones) out through the speakers.

    Dell has replaced both the motherboard and the speakers, and after that which did not help, they said I have to just wait for a new version of the driver.
