Sound glitches after the computer wakes from sleep or Hibernation

When I first turn on my computer, sound works fine, but after standby or hibernation there is odd audio 'glitches' each time there is a spike in CPU activity. The seeds just sounds like small clicks and pop, but I find them very noticeable. They are triggered by things as simple as loading a page in a web browser (which reached only ~ 30% CPU usage on my computer).

Here's what I discovered by just my own tests:

* Happens in programs that use DirectSound and WaveOut. (I think almost all programs use DirectSound, right?)

Programs that use his alternative such as the ASIO API are not affected. I've tested it using foobar2000.

* When recording my sound output using Audacity, clicks and POPs are included in the record. (I can download it somewhere if you want to hear exactly the kind of glitches that I'm talking about).

These facts lead me to believe that the program exists somewhere in the code of Windows Audio (ie. not a hardware or driver problem).

A few things here that I tried to solve the problem:

To restart the "Windows Audio" service.

Stop service "Windows Audio", go to sleep, wake up, start the service 'Windows' Audio.

* Updated my audio drivers

Using the default windows audio drivers

The seeds still exist when I try these. The only thing that solves the problem is to restart the computer.

The most obvious permanent solution to this problem is simply not to use mode 'sleep', but I should be able to use the "sleep" without these problems. I hope just this problem is fixable by me, because after all, I lived in an attempt to solve this problem, I'm afraid that nothing will work.

OS: Windows 7 Ultimate x 64

Sound: Realtek ALC662 HD Audio

Thanks for the reply again, Umesh. Updating drivers did not work, but I managed to solve the problem.

In my original post, I said sound glitched whenever there was a CPU usage, but today, I realized that it was actually using the network causing glitches. I updated the driver for my network card and now the problem is gone! I don't know what was going on, but at least it works now!

  • Fallout 3 stops working after the computer wakes from sleep

    Since the games for Windows Live 3 is out, Fallout 3 has never been the same. He used to work at best my GfWL and now her nightmare. Recently, after that I quit the game and put my computer to sleep, Fallout 3 will stop working completely after wake up. I try to start it and I get them all is a cursor with a small blue rotating light. What is even more strange, is that my computer goes into a State of semi who no longer meet this point where programs and keyboard shortcuts no longer work, but I can browse my hard drive. I try control + SHIFT + ESC to see what the devil but that causes Windows Explorer to stop working. CTRL + Alt + Delete does not work either. No matter what I try, once I start Fallout 3 after the computer wakes from sleep, I can't do the task to the top manager and I can't use my computer.

    Method 1

    I suggest that you manually download and install the latest drivers for display on the computer card and check if it works.

    Method 2

    If the previous step fails then I suggest that you try 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.

  • Computer wake from sleep

    Installed windows 8, the hard drive goes to sleep after 30 minutes as shown in default. When I try to turn on the computer, it looks like the power lights but screen does not work. What's wrong?

    "gigabyte z97x game 5 motherboard running only a 240GB SSD, with an Intel i5 4690 k and a R9 280 X diamond."

    Strange coincidence, I pretty much have this configuration. Gigabyte Z97x ud3h, 240 GB SSD, it 4690 k and a R9 MSI x 280. Sometimes it will not wake up from his sleep and made a kind of attempt of electric start then down several times until I make a hard stop. When it finally starts it resumes where it left off. Just started happening, but I just installed Win 10 so have not had time to trace it down to hardware or software. Really shocked to see that you have a similar setup.

  • Why Firefox freeze and a box rectangular white happen on my Mac screen after the computer enters mode "sleep"?

    Why found frozen Firefox and a rectangular box on my MacPro screen after that the computer goes into screensaver mode and I come back to type it in again? I Force-Quit Firefox and restart my tabs from scratch.

    It got so annoying that I switched to Chrome for a while, but Chrome is a hoarder of power who wouldn't let me download at Amazon cover for books printed images as I write. I want to go back to Firefox, but the only way to prevent him from dying on me is to keep completely off the screen saver and sleep-ECOMAT modes. It started happening after I installed the new OS from Yosemite, then maybe it is a conflict of some sort.

    Here is a screenshot of the appearance of the white box on the Firefox screen frozen. Well, hmm. It seems that this image be download! Well!

    Anyone know what the problem is or how to fix it?

    Hello

    Try Firefox Safe mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that temporarily disables hardware acceleration, restores some settings and disables add-ons (extensions and themes).

    If Firefox is open, you can restart Firefox Safe mode in the Help menu:

    • Click the menu button

      click Help

      then select restart with disabled modules.

    If Firefox does not work, you can start Firefox in Mode safe as follows:

    • On Windows: Hold down the SHIFT key when you open the desktop Firefox or shortcut in the start menu.
    • On Mac: Hold the option key during the startup of Firefox.
    • On Linux: Exit Firefox, go to your Terminal and run firefox-safe-mode
      (you may need to specify the installation path of Firefox for example/usr/lib/firefox)

    When the Firefox Safe Mode window appears, select "start mode safe."

    If the problem is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme or hardware acceleration. Please follow the steps described in the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

    When find you what is causing your problems, please let us know. This might help others with the same problem.

    When my laptop is on battery power and idle for a while, it goes into sleep mode. When I want to start working again, Windows does not accept my password. I need to change username, then click on my profile (which displays LOCKED) and only then Windows accept my password.

    After doing a search on the net, I see other Windows 7 users have the same problem...

    Hi Sean, the problem may be that the NumLock key is on in your profile.

    Try this.  Hit the key Windows and r and type regedit and click ok.  Go to HKEY_CURRENT_USER\Control Panel\Keyboard and locate the InitialKeyboardIndicators value.  DoubleClick on it and change the value from 2 to 0.  Click ok and restart.

  • eHome IR transmitter fails to wake from sleep

    I am running Windows 7 64 bit on an HP box bought less than a year ago.  A Hauppauge 2250 tuner card is installed.  The tuner card is connected to my Comcast Cable box by an IR transmitter.  The system worked well for months, but now I find that the IR Transmitter is not working after coming out of sleep mode.  Reboot and everything works well again.

    How can I get the IR transmitter to continue functioning when the computer wakes from sleep?

    first thing to do is to try a system restore to the last time it worked.

  • Switches to color when you restart the computer profile or wakes from sleep

    I bought a Dell Inspiron 1470 with Windows 7 at home as a backup of my MacBook Pro.  I used the Spyder2Express to calibrate my screen that works well.  After that I restarted my PC the color profile has been enabled for a few short seconds, but then returned to the default setting, which is horribly blue and too bright.

    I then removed the color profile created by my Spyder2Express and used Windows' built in the calibration of the monitor.  Yet once, it worked until I rebooted the computer, or he woke from sleep mode.

    I then wen to the control panel-->--> the color management advanced and assured the new profile is the default value of the system.  The problem still remained after the computer is restarted.

    The only solution I have found so far is if after I restarted my pc I go to Panel of--> of color management and select and clear the checkbox "use my settings for this device."  My profile will then return until I restart the next time.

    As a pro photographer, it is a question that is extremely disappointing.  I searched forums, web, called Dell directly and none of this was of no help.  Any thoughts?

    Hi Mike,.

    It seems that software Spyder2Express adds color profile after each reboot. We can check if really Spyder2Express is the origin of the problem

    Method 1:

    Uninstall Spyder 2 express and check if the return of the issue after each reboot.

    Method 2:

    Configure the computer to boot and then refine the boot entry that is causing the problem

    Step 1: Perform a clean boot:

    Note If the computer is connected to a network, network policy settings may prevent you from following these steps. We recommend strongly that you do not use System Configuration utility to change startup options on the computer, unless a support engineer Microsoft directs you to do so. This can make the computer unusable.
    a. log in the computer using an account with administrator rights.
    b. Click Start, type msconfig.exe in the start search box and press ENTER to start the System Configuration utility.
    c. If you are prompted for an administrator password or for confirmation, type your password, or click on continue.
    d. under the general tab, click Selective startup, and then clear the check box load startup items. (The check box use the file Boot is not available.)
    e. on the Services tab, click to select the skin all the Microsoft services check box, and then click Disable all.
    Note following this step lets Microsoft services continue to operate. These services include networking, Plug-and-Play, record of events, error reporting, and other services. If you disable these services, you can permanently delete all restore points. Do not do this if you want to use to restore the system with the existing restore points.
    f. click OK and then click on restart.

    Step 2: Enable half the services

    a. click on the Services tab and then click to select the skin all the Microsoft services checkbox.
    b. Click to select half of the check boxes in the Service list.
    c. click OK and then click on restart.
     
    Solve the problem:
    After you determine the startup item or the service that is causing the problem, contact the manufacturer of the program to determine if the problem can be solved. Or, run the System Configuration utility, and then click to clear the check box of the element of the problem.

    Reset the computer to start as usual:
    When you are finished troubleshooting, follow these steps to reset the computer to start as usual:
    a. Click Start, type msconfig.exe in the start search box and press ENTER.
    If you are prompted for an administrator password or for confirmation, type your password, or click on continue.
    On the general tab, click the Normal startup option, and then click OK.
    When you are prompted to restart the computer, click on restart.

    All the steps above to perform the clean boot is mentioned in the following article

    Hi George,.

    From the description of the problem, it seems that the computer would not wake from sleep when you close the lid and open it again. I understand the inconvenience.

    Let us, try to perform the following methods and check if it helps.

    Method 1: Run the troubleshooter of power

    Open the troubleshooter of power

    Method 2: Troubleshoot wake the computer from sleep mode

    http://support.Microsoft.com/kb/266283

    Method 3: Update Chipset drivers

    Download and install the latest version of drivers for chipset for the computer on the computer manufacturer site and check if you are faced with the same question.

    Method 4: Run the BIOS update

    I would say as you perform the update of the BIOS by contacting the manufacturer of the computer, check if it helps.

    Important: Change (CMOS) BIOS/complementary metal oxide semiconductor settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

  • (Redirected) Reference DELL 5547 Fan starts while that closed down and drains the battery at 0%, especially may not wake from sleep

    Hello

    When I turn off my laptop the fan starts to spin then and during a night, it drains the battery from 100% to 0. I also have some problems of marketing. If the computer is in sleep mode itself or by me, I can't wake up, need button for 10 seconds and then push again and it starts. When turned on, it works perfectly but has these problems. I read somewhere that the resolution of these problems has been to remove the software intel from my computer and I did. It helped but 2 days computer started having these problems again. My system is Windows 7 64 bit. This problem started after that I have somehow left fully charged computer asleep on the charger for about 2 hours. When I came back fan was spinning and the right side of the laptop was hot. Again, battery life is great and computer has no defects during the work (all tests by dell are passed). What can you suggest me to do?
