Microphone Level is Auto Adjusting on Windows 10

What is causing the Microphone Levels to Auto-Adjust on Windows 10?

We investigated this particular issue by looking at various user reports and the repair strategies that are commonly being used to resolve this particular issue on Windows 10. As it turns out, there are several different culprits that have the potential of producing this problem:

  • Skype is automatically adjusting the microphone – If Skype (UWP or desktop version) is configured to launch at every system startup, chances are that’s you’re the culprit responsible for the automatic microphone adjustments. In this case, you should be able to resolve the issue by disabling the automatic microphone adjustment settings.
  • Steam is automatically adjusting the microphone – Just like Skype, Steam is also capable of automatically adjusting the microphone if it’s configured to be launched at every system startup. If this scenario is applicable to your situation, you should be able to resolve the issue by accessing the Friends List settings and disabling Automatic Volume/gain control.
  • An application takes exclusive control of the microphone  – Another possibility is a different application that is allowed to take exclusive control to the recording device and adjust it’s level automatically. In this case, you should be able to resolve the issue by disabling exclusive mode or by booting in clean mode to identify the culprit.
  • Microphone level is not manually adjusted – Windows includes a toggle that should allow you to override any application that might be adjusting the microphone level automatically. Several affected users have reported that using this procedure allowed them to resolve the issue indefinitely.
  • Outdated or corrupted microphone driver – An improper driver can also be responsible for this particular microphone problem. As it turns out, an outdated driver has the potential of triggering this behavior (the same goes for a corrupted driver). In this case, you should be able to resolve the issue replacing the current microphone driver with the latest version available.
  • Malware infection – THis particular issue can also be caused by a malware capable of shutting down the microphone or adjusting the level to a maximum level at all times. Several affected users have reported that they managed to find the virus and deal with it by performing a Malwarebytes scan.

Method 1: Preventing Skype from automatically adjusting the microphone (if applicable)

If you have the habit of keeping Skype open most of the time, chance are the VoIP client is actually adjusting your microphone levels without telling you. As it turns out, Skype is configured by default to be allowed to modify the volume of your connected microphones. This happens with both the desktop and the UWP version of Skype.

Method 2: Preventing Steam from automatically adjusting the microphone level (if applicable)

As it turns out, Steam is yet another application that might be causing automatic microphone level adjustments on a Windows 10 computer. If you have Steam installed and it’s configured to launch automatically at every system startup, chances are it has the capabilities to make microphone level adjustments.

Several affected users have reported that they managed to resolve the issue by accessing the Friend List’s settings of the Steam client and disabling the Automatic volume/gain control setting from the Automatic Settings menu.

Method 3: Preventing applications from taking exclusive control of the Microphone

Several affected users have reported that they managed to resolve the issue after re-configuring the MIcrophone settings so that no application is allowed to take exclusive control of the device. This procedure is quite easy to replicate and is effectively disables any type of 3rd party intervention that might cause the automatic microphone level adjustments.

  5. Then, from the next screen, click on Search automatically for updated driver software and wait to see if the utility manages to find a new driver version for the driver.
  6. Once the procedure is complete, restart your computer and see if the automatic microphone level adjustments are still occurring. If they are or Device Manager has been unable to find an updated version of the driver, continue with the steps below.
  7. Follow step 1 to 3 again to return to the Driver tab of your Recording device, but this time click on Uninstall Device instead of Update Driver. Then, click Uninstall once again at the confirmation prompt and wait for the procedure to complete.
  8. Once the recording driver is uninstalled, restart your computer to allow Windows Update to install a clean driver instead of the one you’ve just uninstalled.

Method 6: Removing the Malware Infection

As it turns out, this particular issue can also be caused by malware that is capable of shutting the mic or adjusting the level automatically. Several affected users have reported that Windows Defender and a few other 3rd party clients didn’t manage to discover the malware when they performed a security scan.

However, most users that encountered this issue have reported that they managed to identify and isolate and quarantine the malware by using Malwarebytes. In most cases, the malware made it’s way to the system from a catcher application or extension.

Method 7: Performing a Clean Boot

If you’ve come this far without a result, it’s possible that the issue is being caused by a 3rd party application that has admin access. If the culprit is not apparent to you, you can verify whether a 3rd party app is causing the problem by performing a clean boot.

Several affected users have confirmed that this procedure allowed them to confirm that the issue was being caused by a 3rd party app intervention. Once they managed to confirm that an application was causing the automatic microphone adjustments, they eliminated all potential culprits until they managed to isolate the application that was producing the error.

Here’s a quick guide on how to perform a clean boot in order to determine which application is causing the automatic microphone adjustments:

  1. First, start by ensuring that you’re using a Windows account that has administrative privileges.
  2. Then, press Windows key + R to open up a Run dialog box. Inside the text box of the Run command, type “msconfig” and press Enter to open up the System Configuration window. When you’re prompted by the UAC (User Account Control), click Yes to grant administrative privileges to the System Configuration window.
    Running MSCONFIG from a Run dialog box
  3. Once you manage to get inside the System Configuration window, select the Services tab from the ribbon bar at the top and start by checking the box associated with Hide all Microsoft services. Once you’ve down that, turn your attention to the remaining services. Click the Disable all button to prevent any 3rd party services from interfering with the microphone levels at the next startup.
    Disabling all Windows services
  4. Click Apply changes, then select the Startup tab and click on Open Task Manager.
    Opening the Task Manager via System Configuration
  5. Once you’re inside the Startup tab of Task Manager, select each service individually and hit Disable to prevent it from running at the next system startup.
    Disabling Apps from Startup
  6. Once all necessary items and services have been disabled, close the Task Manager window you’ve just opened and restarted your computer to boot up into a Clean Boot State.
  7. Once the next startup sequence is complete, use your computer normally and see if you’re still noticing automatic microphone adjustments. If you aren’t, follow steps 3 to 5 and systematically re-enable all startup items & services that you disabled and reboot to see which one of them is causing the error.
  8. When you manage to identify the culprit, ensure that it remains disabled.

Method 9: Registry Fix

Sometimes, the issue lies with the registry configuration of the microphone level. Windows might have stored a value in the registry for your Microphone level which might receive precedence over the manual value that you select from the Sound Control Panel. You can adjust this value by:

  1. Press “Windows” + “R” to open the run prompt, type in “Regedit” and press “enter”.
    regedit.exe
  2. Navigate to the following location.
    HKEY_CURRENT_USER\Software\Microsoft\Speech\RecoProfiles\Tokens\{95CF724E-B3B5-4D94-A4FB-36AE77A88FE0}\{DAC9F469-0C67-4643-9258-87EC128C5941}\Volume
  3. Double click on the following value.
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Speech\AudioInput\TokenEnums\MMAudioIn\{0.0.1.00000000}.{e4e24557-c9f8-46f6-8486-50981fcf3cc5}
  4. Set its value to the Microphone level that you want. For Example, 8888 for 88% and 2222 for 22%.
  5. Check to see if the issue persists.
