    Windows 8.1

    Microphone constantly muting itself for no reason.


    Found my mic in recording devices! and my friend can hear me. But it keeps muting itself! I had this problem before with another mic, but I don't really remember how to fix it. Help? Allow Other apps to take exclusive control is off, I disabled Automatically adjust microphone volume in skype, I set the Communications option (On another mic) To Do Nothing. Theres no svchost.exe under my name, and yes i've tried restarting. What's going on?

    Follow the steps as below and check if that resolves the issue.
    1. Right click on the volume symbol, on the right bottom corner.
    2. Click on play back devices.
    3. Go to communication and check do nothing.


    You can also check with following steps:


    Method 1:
    Testing for an audio signal

    1. Click Start, and then Control Panel.
    2. Click Hardware and Sounds, and then click Managing audio devices...
    3. Click the Recording tab.
    4. To test the microphone, speak into it. To test line-in, send a signal to the line-in port from the source audio device (press play from the audio player). Look at the gray bars next to the device name on the recording tab:
    5. If the gray bars next to the device name change to green, this device is active and an audio signal is being passed through the microphone or line-in port. This step shows that problem is related to sound settings in the software that uses the microphone. If you have not already done so, set the selected device to default and adjust the levels. Once the device is set to default and the levels are set, use and adjust the sound recording or voice carrying software.
    6. If the gray bars remain gray and inactive, the device is not recognizing a signal. Leave the recording tab open and go to the next step.


    Method 2:
    Check volume levels and mute.

    1. Click Start, and then click Control Panel.
    2. Click Hardware and Sound.
    3. Click Sound.
    4. Select Speakers, and then click Properties.
    5. Click the Levels tab.
    6. Click the Muted button next to Microphone and any other line-in that is muted.
    7. Use the slider bar to raise the level for Microphone and each line-in to at least 75.
    8. Click OK.
