W540 - mute Microphone does not work

I have a new W540 and microphone mute button does not work correctly. When I press fn + f4. the red LED lights up, the microphone off on appears on the display and volume for the "Microphone" and "External microphone" controls are muted in Windows. However, always capture the audio from audio microphones and it can be recorded on applications like Skype and Audacity.

Muting manually microhphones through the sound dialog in Windows box has the same effect. The OSD and LED light, but the microphone does not record. From now on, I have found no way to disable the microphone outside the inhibition of sound input in each individual application.

I just tested this, and I get the same result on my W540. Mute microphone lights and Windows says it's dumb, but he is not actually cut.

    Make sure you write down the description and model double click top - tab drivers - write version. Now
    Click on update drivers who cannot do anything like MS is far behind the certification of drivers. Then RIGHT
    CLICK above and UNINSTALL - REBOOT - this will rebuild the driver stack.

    If your driver shows 06 you have the default windows and part of the question.

    Go to the system manufacturer's website and get the latest Audio/Sound drivers - download - SAVE - go to the place where you
    Put them - right click on Reboot - RUN AS ADMIN -.

    Check the Version tab of the driver in the Device Manager as the restoration of the sound card drivers often
    and then install the latest version. Restart and check after each test, not
    rare to have to run the pilot of 1 to 4 times or more. Just the version make sure you
    installed shows upward on the tab of the driver.

    Then navigate to the site of the manufacturer of the device and search for the drivers more recent and repeat the installation procedure.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

  • microphone does not work hp dv6000

    Hey guys,.

    I have hp dv6000 laptop. The microphone is integrated and it doesn't work. It says that the driver is installed correctly but it is obviously not.

    What should I do?

    Thank you

    Hi yassena,

    Thank you for using Microsoft Windows forum.

    I suggest you all to first download and install Windows 7 driver compatibility.  Check your drivers in the Windows 7 Compatibility Center: http://www.microsoft.com/windows/compatibility/windows-7/en-us/default.aspx to check if your audio drivers for hp dv6000 are compatible.

    The drivers for your hp dv6000 seem not to be compatible with Windows 7 and this is why I suggest you to download the Windows Vista Compatible drivers from: http://h10025.www1.hp.com/ewfrf/wc/softwareList?os=2093&lc=en&dlc=en&cc=us&lang=en&product=1842155 and running Windows Vista compatibility mode.

    You can also try to adjust the default microphone and check under the sounds in the recording tab.

    It seems that the microphone is not properly configured on your computer. You can try to solve the problems more microphone/line-in following the steps, in order, to test, check the connections and the hardware, update the audio drivers and configure the audio settings of Windows. If you follow these steps in the correct order, you will fix the problem or you will find that the audio software must be configured or updated.

    Step 1: Test of an audio signal

    1. click on start, then Control Panel.
    2. click on hardware and sound and then click on manage audio devices...
    3. click on the recording tab.
    4. to test the microphone, speak into it. To test the line, send a signal to the line at the port of devices audio source (press play on the audio player). Look at the gray bars next to the name of the device under the recording tab:
    * If the gray bars next to the device name turns green, this device is active and an audio signal is passed through the microphone or line-in port. This step shows that this problem is related to sound parameters in the software that uses the microphone. If you have not already done so, set the device selected by default and adjust levels. Once the device is set by default and levels are defined, use and adjust the sound recording or voice carrying software.
    * If the gray bars remain inactive and grey, the device does not have a signal. Leave the record open tab and go to the next step.

    Step 2: Check the volume levels and mute

    The volume of the speaker to the microphone and line - in may be activated or rejected. Use the following steps to check the volume of speaker for line and microphone levels.

    1. click on start and then click Control Panel.

    3. click on sound.
    4. Select speakers, and then click Properties.
    5. click on the levels tab.
    6. click the button mute Microphone and on any other line that is cut.
    7. use the slider to increase the micro level and each line at least 75.
    8. click on OK.

    Step 3: Update the audio drivers

    You can see a front-end port microphone does not work, a recording device is missing in the recording tab, a microphone is not recognized when it is plugged in, or any other problem. There may be updates audio drivers that can solve this kind of problem. Use the following steps to ensure that the audio drivers are up to date.

    4. right click on the name of the sound material and select software update of the driver...
    5. click on search automatically for a driver updated and wait for Windows to update the driver software.
    6 Windows checks a remote Web site to see if the update of the driver software is available.
    * If an update is available, let Windows install the update.
    * If an update is not available, proceed to the next step.
    7. once the update is successfully installed, test the microphone or line like that was made in step 1. If the problem persists, proceed to the next step.

    Step 4: Configuration of Windows registry settings

    By default, Windows 7/Vista automatically activates microphones and line - in ports. Use the following steps to set the microphone/line-in port to be the default port and configure the logging levels.

    1. If the recording in the Audio window tab is not selected, open the sound and click the recording tab and make sure the State is defined as below.

    1 - port microphone - work and set as default

    2 - line In - work

    3. digital (S/PDIF port) In - work

    4 - stereo Mix (mixer software) - disabled

    1. If several microphones or line - in ports are available, select the port you want to use. Click on set as default to make this device default audio input device.
    2. If the device you want to use contains a small circle with an arrow pointing down, the device is disabled. To activate the device, right-click the device name, and then select activate.
    3. once the selected device, click Properties, and then click the levels tab.
    4. adjust the slider up to 75% of its range.
    5. If the mute is enabled, click the button mute to reactivate the device. The mute button should show as a blue speaker without any red circle.
    6. If the Microphone Boost is available, adjust and + 20.0 dB.
    7. click OK to make the changes.
    8. test the microphone as was done in step 1 to determine if Windows is able to detect a signal from the microphone or line used. If you have completed all the steps and the microphone or the source device still does not work, the audio ports or the computer's sound hardware can be bad.

    Hello Bllacke,

    Thank you for using communities of Apple Support.

    I see from your post, some applications have a problem to access your Microphone. I know how it is important to ensure that your applications have access to the Microphone and can use this feature. I have a few things I want to try.

    First, tap Settings on your iPhone and then scroll to the last section that lists your apps. Select the applications that use the microphone and make sure that the Microphone is activated (green).

    Then, follow the steps in the article below to close these applications:

    Force a nearby application on your iPhone, iPad or iPod touch

    Then, test the microphone in these applications again and see if it works.

    Best regards.

  • iPhone 5 s microphone does not work during phone call

    Hello! My iphone 5s works really well, sensors, speaker, camera, all right. Similarly, the microphone works really well when I make a call using 'whassapp', 'line', etc and I can record video, talking to Siri, using voice memo and once more my microphone works really well. BUT! When I make call and receive phone call my microphone does not work, they do not hear my voice at all. What will happen with my microphone when you use the cell phone call? HELP ME PLEASE!

    Try resetting your device. This will not erase your data stored on that device.

    • Press and hold the sleep/wake button
    • Press and hold the Home button
    • Press and hold both buttons until the display turns off and on again with the Apple logo on the subject.

    Alternatively, you can go to settings - general - reset - Reset all settings

    If that doesn't work, restore your device to factory settings. Please note that this will delete the data on your device.

    Take a look this Apple Support article: use iTunes to restore the iPhone, iPad or iPod to factory settings - Apple Support.

    As a final step, try recovery mode. Turn off your unit, then plug it to your computer with the hold home button. Hold down Home button until you see the logo of iTunes on the screen of your device. After that on your computer, you should see the iTunes window saying that your device needs to be restored to factory settings. Click Restore.

    Can I get the service locally in India.

    Hello

    The internal MIC is part of the webcam module.
    What happens if you start the webcam, try saving and small clip? The sound recording is this too?

    Usually, you can change the recording devices in Control Panel-> sound-> recording tab
    Here, you can check what devices are available. Right click and check if hidden and disabled devices can be demonstrated.

    By the way: I had some problems with the playback of the sound after installing the Realtek audio driver. I uninstalled the Realtek audio driver and Device Manager remove the audio display Intel (in games, field audio video controller). In the peripheral zone system you could remove the controller high definition audio.
    Again, restart the laptop.

    Usually, removing devices should be recognized automatically. Then go again to the dashboard-> sound-> recording tab and check if other devices outside external microphone are available.

    Hello

    Connect an external microphone to * Headphone\Microphone combo socket *, still records through portable microphone instead of externally. Registration of external Microphone does not work.

    What Miss me? Please notify.

    Model: L50-B916
    Screenshot: http://s12.postimg.org/j8h3v5k4d/laptop.jpg

    I can't say with certainty what may be wrong here, but two things confuse me:
    -somehow your external MIC is obviously not detected because in the case when the external microphone is connected laptop switches automatically to it
    -I don't understand why there are two identical entries under recording devices.

    When I connect my headphone it is always a single entry (Conexant SmartAudio HD default unit), but my machine automatically goes to the external microphone only.

    Have you tested the feature with some applications like Skype?
