11 Ways to fix Microsoft Teams Audio Not Working, No Audio issues

Any service that’s available online has its own set of issues and Microsoft Teams is no exception. The collaboration tool has seen significant growth in its user base amid the COVID-19 pandemic but at the same time, has also seen a handful of issues that might affect your remote working experience on a daily basis.

There have been several reports that Microsoft Teams isn’t able to get access to your microphone’s audio while in a video conference. If participants in a meeting are dealing with No Audio issue on Microsoft Teams, the following list of fixes should help you solve your problem.

Solution #1: Restart your Teams software, PC and phone

Ask anyone how to fix a problem on your phone or PC, their first response will be to suggest you rebooting or restarting the device. Since computers and modern smartphones rely on a RAM (Random Access Memory), when you restart the device, the RAM gets cleared and along with it all the temporary cache and logs that were being generated in the background. So, when a computer or smartphone restarts, most common problems are solved or they start with no significant issues.

You can restart your devices by following the methods relevant to you.

Windows: Go to Start button, select the Power button, and then click on ‘Restart’.

Mac: Click on the Apple icon at the top left corner and select the ‘Restart’ option and then click on ‘Restart’ again.

Android: Hold the Power button on your Android device and tap on ‘Restart’.

iOS: Press and hold the side button (and any volume button on iPhone X, XR, Xs, XS Max, 11, 11 Pro, 11 Pro Max) until the power off slider shows up and then drag the slider to the right to reboot.

Solution #2: Check whether you’re muted and if yes, unmute yourself

It’s a simple solution but it’s the first thing you should take into consideration. Inside a Teams meeting, check if the microphone is struck off. If that’s the case, then you might have been silenced by the meeting organizer or you accidentally silenced yourself.

In a team meeting, you can see for yourself if you’ve been silenced if the microphone button has been struck diagonally with a line.

To unmute yourself, click on the microphone icon which should now be unstruck and you should now be able to speak during a meeting.

Solution #3: Verify if your device’s microphone isn’t physically muted

If your microphone isn’t muted on the Teams app, check if your device’s microphone isn’t muted. Some keyboards have a dedicated mute button that blocks audio on both your speakers and your microphone. You thus have to make sure that your audio isn’t physically muted and if it is muted, press the key again to unmute it.

Besides keyboards, some audio devices like headsets with a microphone have native switches to mute/unmute the microphone. Check if your audio is working using an unmute switch on the headset.

Solution #4: Make sure your audio device is selected

You might have more than one audio device connected to your system. So chances are that Teams app hasn’t automatically selected the primary audio device that you may want to use during meetings. To change your audio device on Teams, click on the 3-dots (More options) icon from the meeting controls at the bottom and select ‘Show device settings’.

Under the Audio devices section, select your primary audio device from the drop-down menu. You can also configure your audio set up by individually selecting your preferred ‘Speaker’ and ‘Microphone’ devices. Check if you’re now able to speak during a meeting and if your voice is being heard by others.

If you’re not in a meeting, you can select your audio devices by clicking on your Teams profile picture on the top right corner, heading over to Settings > Devices, and then selecting the device you want to use as your primary speaker and microphone.

Solution #5: Check for audio incompatibility with Teams app

Microsoft has confirmed that Teams will only work with the Microsoft certificated audio devices. If the above solutions do not work, then there’s a likelihood that you’re using an audio device that’s incompatible with the Teams app on your system. You can check if your audio device is eligible to be used with Microsoft Teams from the links below.

Solution #6: Allow microphone access to Teams inside Windows settings

In Windows 10, apps and services need your permission to control some elements of your system like the use of your camera or microphone. This is present so as to protect users from unknown apps and malware that could take advantage of these access points for their own benefit.

If your audio isn’t working, then it might be because the Teams app hasn’t been able to use your computer’s microphone. To enable microphone access for Teams on Windows, click on the Start Menu and head over to Settings > Privacy > Microphone. Inside this screen, make sure that the ‘Allow desktop apps to access your microphone’ option is turned ON.

In addition to that, you should also double-check if you have enabled microphone access to the Teams app under the ‘Choose which apps can access your microphone’ section. If you’re using Teams on the web, make sure the web browser that you use Teams on has access to your microphone as well under this section.

Solution #7: Change the default Recording device on Windows

If your audio device still isn’t working, a user “LiamWard” on Microsoft Answers page suggests a solution that seems to work for a similar problem on Skype. You can use Windows 10’s native ‘Recording devices’ feature to select your default Recording device for all the apps on your computer.

You can do so by right-clicking on the speaker icon in the notification area (on the taskbar) and selecting ‘Recording devices’ from the menu. From here, check if your audio input is selected for default recording purposes. To set a microphone device for default recording, right-click on it and select the ‘Set as Default Communication Device’. If this option doesn’t work for you, you can select “Microphone Array (Realtek High Definition Audio(SST))” as the default Recording device.

Depending on what you chose as the default Recording device, selecting this device as your default audio option inside the Teams app, as listed on the Solution #3 from above.

Solution #8: Change your Mac’s privacy settings

Recent versions of macOS allow you control over which apps and websites can use the microphone in order to capture or record audio. If your Teams app isn’t able to grab your audio from the inbuilt microphone or any other device when using a Mac, then you might not have allowed the app access to your microphone inside Mac’s privacy settings.

To give access to your microphone on a Mac, click on the Apple icon on the top left corner, select System Preferences, and head over to Security & Privacy > Privacy. On this screen, select the ‘Microphone’ option from the left sidebar and check the tickbox next to Microsoft Teams to allow it to access the microphone.

Solution #9: Check whether your problem persists with Teams on the web

If none of the above solutions work and you’re using the Teams using a desktop client on your Windows or Mac commuters then you might want to use Microsoft Teams on the web. The web client of Teams is not only an alternative to its desktop counterpart but also a fully-functional one with support for video calling, screen sharing, and more.

You can use the Teams on the web by going to “” and signing in with your account credentials. At the time of the writing, only Microsoft Edge (Chromium-based) and Google Chrome have full support for Teams while some features are missing on Safari and Mozilla Firefox. Here’s a full list of browsers Teams will work on.

When using a browser to sign in to Teams, you also need to make sure that the selected browser has been allowed microphone access. Take a look at Solution #5 and Solution #7 to give microphone access to your browser on Windows and Mac respectively.

Solution #10: Create a new Windows user profile

In a Microsoft community post, it has been reported that deleting a local Windows profile and creating a new one to use Teams no longer gets you the ‘audio not working’ error.  The suggested was posted by a Microsoft Agent and has been confirmed to work for some users.

To delete a local Windows 10 profile, click on the Start menu and head over to Settings > Accounts > Family & other users. Here, select the profile you want to delete and hit ‘Remove’.

Now create a new profile from within the same screen by clicking on the ‘Add someone else to this PC’ option under the ‘Other people’ section. You can either create the profile using a Microsoft Account or without one. Using this profile, try to use the Teams app and check whether your audio is now working.

Solution #11: Delete all sound devices on Windows

A user posted on the Microsoft Telecommunity that deleting all audio devices on Windows solves the audio not working problem when using Teams. To do this, open the Control Panel on your Windows PC and head over to Hardware and Sound > Device Manager. Right-click on all the sound devices and click Uninstall.

Do this for all the audio devices listed under Device Manager, and then restart your computer. Windows will now scan for hardware changes and only install drivers for currently active components. Restart your computer to apply the changes and check if audio is working inside the Teams app.
