Google Duo Microphone Not Working

Time Needed : 9 minutes

For this problem, you may only have to do one or a couple of procedures to make the microphone work on Google Duo.

  1. Force restart your phone

    It is always possible that this problem is caused by a minor firmware issue. So the first thing you have to do is force restart your phone to refresh the memory and reload the apps and services. 

    1. Press and hold the volume down button and the power key for 10 seconds. This will force your phone to power itself down and turn back on. 
    2. When the logo shows, release both keys and wait until the device has finished rebooting. 

    After the restart, open Duo and try to make a video call to test if the microphone is already working.

  2. Test the microphone

    After doing the first solution and the microphone is still not working when you use Duo, then you have to make sure that it’s not an issue with the microphone itself. 

    Launch the camera and then record a video with you talking. Record just a few seconds and play it. If your voice is captured, then the microphone is working. If not, try opening the voice recorder and record your voice. If it is still not able to capture your voice, then the microphone is defective and you need to have it checked. 

    However, if the microphone is working fine on its own but doesn’t work on Duo, then move on to the next solution.

  3. Check the permission

    What you need to do next is to make sure Google Duo is allowed to use the microphone. You just have to check the permission and make necessary changes. Here’s how it’s done:

    2. Go to the screen where the Duo app is located. 
    3. Tap and hold on its icon until options show. 
    4. Tap App info. 
    5. Scroll down to find Permissions and tap on it.

    7. Make necessary changes and then try using Duo again.
