Well, apart from learning how to make Dalgona coffee, honing our house maintenance skills, and finding amusing new ways. In order to pass the time in this lockdown period (2020). We also have been spending our time on video conferencing platforms or applications. Well. Zoom has been getting the most action, Microsoft Teams actually has emerged as the underdog, and a lot of companies have been depending on it to get work done remotely. Just read this article to know all about How to Fix Microsoft Teams Microphone Not Working. Let’ begin!

Microsoft Teams, apart from permitting the standard group chat, video, and voice call options as well. Also bundles in just a number of other interesting features. The list also includes the ability to share files and collaborate on documents, also integrate third-party addons (to prevent minimizing Teams when their need arises), etc. Microsoft has also replaced the Skype add-in found in Outlook along with Teams add-in. And thus, Teams has now become the go-to communication app for companies that relied on Skype for Business previously.

How to Fix Microsoft Teams Microphone Not Working

There are many reasons that might be prompting your Microphone to misbehave on a team’s call. First, you have to make sure that the Microphone is functional. To do that, connect the Microphone to another device (your mobile phone works as well) and try calling someone; if they are able to hear you loud and clear, the Microphone does work, and you guys can rest assured of no new expenses. You can also try using any other application that requires input from the Microphone. For example, Discord or a different video calling program, and check if it works there.

Also, did you try simply restarting the application as well as plugging the Microphone out and back in again? We know you did, but it doesn’t hurt to confirm. Computer users may also try plugging the Microphone into another port (the one present on the CPU). If there is actually a mute button on the Microphone, just check if it is pressed and confirm that you haven’t accidentally muted yourself on the application call. Many time, Teams may fail to detect your Microphone if you connect it while in the middle of a call. To connect the Microphone first and then place or join a call.

When you have established that the Microphone works just fine and have also tried the above quick fixes. We can move to the software side of things and ensure everything is properly configured as well.

Check App & Microphone Permissions | Microphone Not Working

Whenever executing the above method, some users might not be able to find their Microphone in the drop-down selection list. This basically occurs if the application does not have permission to use the connected device. To give Teams the necessary permissions:

  • Tap on your profile icon present at the Teams window’s top-right corner and choose Settings from the ensuing list.
  • Go to the Permission page.
  • Now, check if the application is allowed access to your media devices (Camera, Microphone, and speaker). Tap on the toggle switch to enable access.

You will also have to check your PC microphone settings and verify if third-party applications can use it. Many users disable microphone access out of concern for their privacy, however, they forget to re-enable it when required.

  • Tap on the Windows key to bring up the Start menu and then click on the cogwheel icon to launch Windows Settings.
  • Tap on Privacy.
  • Now under App Permission in the navigation list, just tap on the Microphone.
  • At last, ensure the toggle switch for Allow apps to access your Microphone is all set to On.
  • Just scroll down further on the right-panel, locate Teams, and just check if it can use the Microphone. You also have to enable ‘Allow desktop apps to access your microphone.

Run the Microphone Troubleshooter 

Those were all the settings that you could have checked and also corrected to get the Microphone to work in Teams. If the Microphone still refuses to operate, then you can try running the built-in microphone troubleshooter. The troubleshooter will now automatically diagnose and fix any issues.

To run the microphone troubleshooter – Go to Sound settings (Windows Settings > System > Sound). Scroll down on the right panel in order to find the Troubleshoot button, and click on it. Make sure you tap on the Troubleshoot button under the Input section since there is a separate troubleshooter available for output devices (speaker & headsets) as well.

If the troubleshooter does find any issues, then it will inform you about the same along with its status (fixed or unfixed). Close the troubleshooting window and check if you guys are able to resolve the Microsoft Teams Microphone not working issue.

Verify if the Microphone is enabled in PC settings 

Continuing along with the checklist, just verify if the Microphone is on. If it isn’t, then how are you going to use it? We will also have to make sure the desired Microphone is set as the default input device if there are multiple microphones connected as well.

  • Just open Windows Settings (Windows key + I) and tap on System.
  • Using the navigation menu on the left, you can now move to the Sound settings page.

Note: You can also access Sound Settings by right-clicking on the Speaker icon on the taskbar and then just selecting Open Sound Settings.

  • Now, on the right panel, just tap on Manage Sound Devices under Input.
  • Then under the Input Devices section, just check the status of your Microphone.
  • If it’s disabled, then tap on the Microphone in order to expand sub-options and activate it via clicking on the Enable button.
  • Now, head back to the main Sound settings page and just locate the Test your Microphone meter. Speak something directly into the Microphone and then you can check if the meter lights up.

Ensure the correct Microphone is selected

If you have multiple microphones connected to your computer, it is really possible for the application to choose the wrong one mistakenly. So while you guys are speaking at the top of your lungs in a microphone, then the application is looking for input on another microphone. To make sure you select the correct Microphone:

  • Open Microsoft Teams and then place a video call to a colleague or a friend.
  • Tao on the three horizontal dots present on the video call toolbar and choose Show device settings.
  • Just in the following sidebar, just check if the correct Microphone is all set as the input device. If it isn’t, expand the Microphone drop-down list and also choose the desired Microphone.

When you choose the desired Microphone, just speak into it, and then check if the dashed blue bar below the drop-down menu moves. If it does, you can then close this tab and (sadly) get back to your work call as the Microphone is no longer dead in Teams.

Update Audio Drivers

We have also heard this time, and again that corrupted and outdated drivers can actually cause a connected device to malfunction. Drivers are software files that external hardware devices use in order to communicate with the operating system. If you guys ever face any issues with a hardware device, then your first instinct should be to update the associated drivers. SO update the audio drivers and now check if the microphone issue gets resolved.

  • Tap on Windows key + R to open the Run command box, type devmgmt.msc, and tap on Ok to open Device Manager.
  • First, expand Audio inputs and outputs via clicking on the arrow to its right—Right-tap on Microphone and select Update Driver.
  • Just, in the following window, choose Search Automatically for drivers.
  • 4. Also, expand Sound, video, as well as game controllers and update your audio card drivers.

Restart your PC and see if you’re able to fix the Microphone not working on the Microsoft Teams issue.

Reinstall/Update Microsoft Teams | Microphone Not Working

At last, if the microphone not working issue wasn’t fix via any of the above methods. Then you should try reinstalling Microsoft Teams altogether. It is also possible that the issue is caused because of an inherent bug, and the developers have already fixed it in the latest release as well. 

  • Open Control Panel through typing control or control panel in either the Run command box or the start menu search bar as well.
  • Tap on Programs & Features.
  • In the following window, just find Microsoft Teams (tap on the Name column header in order to sort things alphabetically and also make looking for a program easier), right-tap on it, and choose Uninstall.
  • A pop-up requesting confirmation on the action will now arrive. Tap on Uninstall again in order to remove Microsoft Teams.
  • Just fire up your preferred web browser, then visit Microsoft Teams, and now download the installation file for desktop.
  • When you download, click on the .exe file in order to open the installation wizard. Then follow all the on-screen instructions to re-install Teams as well.
