Why Is Your Microphone Not Working on Messenger?

If you are on a video call on Messenger and your friend cannot hear you, despite no disruptions in your video, then know you are not the only one encountering this issue.

Many Messenger users have complained lately on various platforms and forums that their microphones do not work during Messenger calls.

However funny it may seem when your lips are moving, but no words come from your mouth (like in silent movies), it is frustrating for people experiencing it. 

If you come across these situations — no need to panic! Take a deep breath and look for the reasons triggering this issue to fix them. 

For that, follow our this guide!

Reason #1: Check Messenger Permissions

If you are accessing the Android or iOS app of Messenger, during the installation of these apps, you need to grant some permissions. Facebook Messenger requires permission to access your camera, microphone, and contacts. 

Any permission not granted will affect any feature that uses that utility.

For example, if you do not give access to the camera, your friend will not be able to view your video during the video call. Similarly, if you do not grant permission to the microphone, it will affect your audio.

To give permission to the Messenger, follow these steps:

  • For iOS: Go to “Settings”Messenger > turn the toggle on next to “Microphone”.Settings Messenger Microphone
  • For Android: Go to “Settings”“Apps”Messenger > “Permissions”> tap on “Microphone” and check “Allow”. Allow Microphone Permission Messenger

If you are using the desktop version of Messenger, check whether your microphone is enabled in “System Settings” and functioning properly.

Reason #2: Check for Other Conflicting Apps or Software

If something is working in the background that also uses a microphone, like Zoom, this app must be conflicting with your microphone on Messenger.

So, shut the app properly from the background on all your devices to see if it resolves the issue.

  • On iOS – open the App switcher to open the window of all opened apps in the background. Find the conflicting app card and swipe it up to close it.App Switcher Close App
  • On Android – open the “three vertical lines” at the bottom screen and swipe up the conflicting app card to close it. Alternatively, you can go to “Settings” and “Force Stop” the app. Swipe Up The Conflicting App Card
  • Windows users can right-click on their taskbar and select “Task Manager” to end any app using the microphone besides Messenger. Task&Nbsp;Manager Microphone Usage
