How to fix a Zoom microphone that doesn’t work

Have your teammates often told you that they can’t hear you in Zoom? And you may be wondering what’s wrong with your computer. Are you wondering what’s wrong with the microphone or audio in the Zoom app on your computer? Find out the answer in this post, where we will tell you how to fix the Zoom microphone not working on your Windows 10 computer.

Audio plays an important role in long-distance calls and video conferencing. If that doesn’t work for anyone these days, when nearly half the world works remotely because of the COVID-19 pandemic, all hell will break loose.

Let’s see how to solve the sound problems in the Zoom app.


What makes Zoom’s microphone not work

What makes Zoom's microphone not work

While reviewing customer feedback from network support, we found a list of reasons for this problem, which is as follows:

  1. Microphone Off: In many cases, users are not technicians. Therefore, it is possible that their microphone is disabled in Windows or Zoom settings (without their knowledge), which ultimately leads to this problem.
  2. Device connection errors: Sometimes when we connect microphones to a computer through a USB port or 3.5mm jack, the system initiates connection processes in the background. When these processes fail, the microphone is not added to the Windows devices and Zoom cannot use it for meetings.
  3. Correct Zoom: Sometimes installation errors are not visible enough to be noticed. Users don’t get any warning messages, but some program files are corrupted, which can lead to many errors. If Zoom installation fails, you will most likely get this error.
  4. Other: This may be due to hardware bugs, outdated drivers, detection issues, etc.

All of the above reasons are the result of extensive online research by our technical researchers. Now let’s move on.

Here's how to solve the problem of the Zoom microphone not working

Allow access to the microphone

If you’re using Windows 10 and the Zoom microphone isn’t working, your apps probably can’t access it. To allow Zoom to use the microphone, follow these steps:

  1. On your keyboard, press the Windows logo key, and I’ll open the Settings menu at the same time. Then click on “Privacy.”
  2. On the left pane, scroll down and click Microphone.
  3. Click Edit and make sure microphone access is enabled for this device.
  4. Enable the option that allows apps to access the microphone.
  5. Scroll down to Allow desktop applications to access the microphone section and make sure this setting is enabled.

You now have access. Next, check to see if your microphone can pick up your voice as expected. If not, please move on to the next solution.

Check your microphone settings

Incorrect settings, such as mute the microphone or not having it as the default device, or the volume is too low, will prevent normal use of the microphone in Zoom mode. Follow the instructions to configure all settings correctly.

  1. On the keyboard, press the Windows logo key and R at the same time to open the runtime window. Then enter the control and press OK.
  2. Select Small Icons from the drop-down menu next to Show By. Then click on Sound.
  3. Click on the Record tab. Then right-click on the empty area and check the Show Disconnected Devices checkbox.
  4. Make sure your microphone is turned on. If it is not, right-click on it and click on Enable.
  5. Check to see if the microphone is set as the default device. If it is not, click on it and click Set Default.
  6. Right-click on the microphone and select Properties.
  7. Select the Levels tab. If the microphone is off, click on the speaker icon to turn it back on. Then drag the slider to set the maximum microphone volume.
  8. Click OK.

After making the above settings, the microphone should work properly. You can simply run a microphone test on Zoom to check. If the problem persists, move on to the next solution.

Update your audio driver

One of the most common reasons for Zoom’s microphone not working is an outdated or faulty audio driver. To keep your audio devices in top condition, you need to install the latest audio driver.

There are two ways to update the audio driver:

Manual driver update: You can go to the manufacturer’s website and search for the latest driver versions. After downloading the correct driver for your version of Windows, follow the instructions on the screen to install it manually.

Automatic driver updates: If you don’t have the time, patience, or computer skills to update your drivers manually, you can do it automatically with a third-party driver update program. The third-party driver update program will automatically detect your system and find, download, and install the correct drivers for your audio device and Windows version.

Changing Scale Audio Settings

If your microphone works fine with other programs and you’re only having problems with Zoom, it may be due to the sound settings in the app. You can adjust the settings as follows and see if the input device comes back.

  1. Start Zoom. Then click the gear icon in the upper right corner to access the zoom settings.
  2. Click on the Audio tab and select the desired microphone from the drop-down menu next to the microphone.
  3. Check the Automatically connect computer audio when you join a meeting box.
  4. Click the Advanced button.
  5. Configure the settings as described below:
    Remove persistent background noise: Moderate or Off.
    Remove intermittent background noise: Moderate or Off
    Cancel echo: Auto

Come to the meeting to see if your microphone is working now. If you see a microphone icon with a red line in the bottom bar, it’s off, and you must click the icon to turn it off before other attendees can hear you. If the microphone problem is still unresolved, see the last solution.

Setting the Zoom

If none of the above solutions help, consider reinstalling Zoom, as this will solve the basic problems with the application itself.

  1. On your keyboard, press the Windows logo key and R at the same time to invoke the Run command. Then type appwiz.CPL and press OK.
  2. Right-click on Zoom and click on Uninstall.
  3. Follow the instructions on the screen to complete the uninstall process. Then download Zoom from the official website and install the new application on your computer.
