Fixing the Constant Auto Muting of Microphone in Windows 10

Many people encounter the constant auto muting of microphone (internal and external). While this problem is most common in Windows 10, the microphone can also stop working properly in older Microsoft products. Usually, the microphone works fine for a long time, but then it arbitrarily disconnects and resets.

According to Microsoft experts, this may be due to improper sound settings or outdated device drivers. However, you should not exclude the version of malware/virus infection either. So, if you can’t talk on Skype or record anything properly because your microphone automatically mutes, try the effective methods we’ve listed below.

What Causes the Microphone to Turn Off Automatically?

When something like this happens, it would obviously be helpful to know the immediate cause. If the microphone keeps dropping despite your attempts to adjust it to a certain volume level, here are the likely causes:

Incorrect sound settings on the system: most of us don’t need to make special sound settings in Windows 10. Just use the volume controls to turn the sound up or down at any time while watching TV, playing games, streaming, chatting, or recording.

If the sound keeps disappearing, the system volume may have been unknowingly set to “mute.” Most likely, the internal or external microphone has been disabled, preventing sound from flowing through that device. Other inappropriate sound settings may have a similar effect.

Malware corrupted sound files: Many system files play a role in providing sound input. When these files are attacked by malware, they cause various sound problems, including accidentally disabling the microphone.

The sound drivers have not been updated: If you are experiencing this sound problem on a computer that has gone through better days, it may be that the sound drivers have not been updated in a long time. If you have recently upgraded or updated your operating system, your current sound drivers may no longer be compatible with the firmware. Only compatible device drivers can be used by your PC hardware, such as video, sound, and network cards.

Incompatible PC drivers may not work at all. If they do work, they are usually not working correctly, leading to all sorts of bugs, such as the problem of the microphone turning off automatically.

Now that we’ve explained the possible causes of accidental microphone disconnection in Windows 10, let’s look at possible solutions prepared by Techquack.

How to Repair the Constant Auto Muting of Microphone

Update your microphone device driver

As mentioned above, an outdated sound driver is also the cause of microphone disconnection in Windows 10. To solve this problem, you can try to update the driver by following these steps:

  1. Right-click on the Start button and select Device Manager from the context menu.
  2. Expand the Sound, Video, and Game Controllers category, then right-click the audio device you want to update and select Update Driver.
  3. Select the option Automatically check for driver software updates.
  4. Then follow the on-screen instructions to complete the update.
  5. Windows will then automatically check for available updated drivers and install them for you.
  6. You can also download the driver for your audio device from the manufacturer’s website and install it on your computer.

Correcting improperly configured settings

If after several scans you are convinced that no malware is running on your computer, the problem may lie in your Windows settings. We’ll try to show you the correct settings needed for your microphone to work properly.

  1. Locate the volume icon on the right side of the taskbar, right-click it, and open Playback Devices.
  2. Click the Communications tab and click the Do Nothing radio button.

If that doesn’t solve your problem, you can try testing the microphone to see if the problem is with the device or with Windows.

  1. Open the Control Panel by searching for it.
  2. Use the category view and click Hardware and Sound.
  3. Under Sound, open Manage Audio Devices.
  4. Switch to the Record tab and make any sound.
  5. If green bars appear, the device is working properly and the problem is not hardware-related.
  6. If the bars remain gray, your microphone may not be working properly and you need to repair or replace it.

The last method of setting up Windows solves the problem if you accidentally disabled one of the microphones or speaker devices.

  1. Go to the Hardware and Sound section of the Control Panel, following steps 1 and 2 of the previous method.
  2. Click on Sound and click on the Playback tab.
  3. Click on Speaker and open its properties by clicking on the button below.
  4. Click on the Levels tab and disable the Mute button if it is active, and use the slider to set the microphone level to no lower than 75.
  5. Check to see if the problem persists.

Change the microphone format

Some users report that changing your microphone format may solve the problem. Try this. To do so:

  1. Open the Sound Control Panel again using the method described above, then select Silent Microphone and click Properties.
  2. Click the Advanced tab and select the format of the other 16-bit parameters from the drop-down list.
  3. Click Apply to save your changes.

Stopping Svchost.exe processes

The microphone is disabled when malware interferes with your microphone. Svchost.exe is one of the most common processes that can disable your microphone. If the svchost.exe file is consuming more than 30% of your CPU or memory, this process is likely causing the problem.

  1. Press Ctrl + Shift + Esc to open Task Manager, then click the Details tab and sort the processes in alphabetical order.
  2. Check to see if the svchost.exe processes are consuming a lot of CPU.
  3. If so, you should terminate those processes.
  4. Type cmd in the search box, then right-click the Command Prompt application and select Run as administrator.
  5. In the window that appears, type the following command and press Enter to kill all svchost.exe processes.
  6. taskkill /F /PID #### (Replace #### with the four digits in the PID column of the Task Manager).
  7. Now check if the microphone keeps going off or not.
