Now you know why Zoom audio cut out, so let’s discuss how you can resolve this issue permanently. Here, we have collected a few verified quick methods to eliminate the problem and enjoy smooth Zoom calls and meetings.

Check Microphone

It must be your first step before checking your drivers or application settings. Next, check whether your microphone works properly by plugging it into a different device and testing it. If it doesn’t work in any other application or device, it’s time to buy a new one without waiting any time. 

Mics often get damaged by their plugs or after being used for a long time. You should check them carefully for damage and replace them if necessary. Here are a few tips to keep in mind when checking your microphone:

  • Check the microphone’s wire thoroughly.
  • Try a different working microphone.
  • Connect the microphone to another device.
  • Test microphone using Windows microphone’s test.

Running a microphone test on Windows is easy, and anyone can do it. This test ensures whether the device is working properly or not. You don’t have to go for a new one if the audio signals pass without interruption. 

  • Go to the Windows search bar, search “Sound Settings,” and open the settings. 
  • Scroll a little bit down. Here, you will find the “Test your microphone” option. 
  • Now tap on your microphone; if you see the blue line moving back and forth, your microphone works fine.

  • The microphone is not responding properly if there is no blue line.

Check Speakers

Speakers are also an important part of the conversation. There is a possibility that the speakers are stuck, which would explain why you do not hear any sound. Therefore, to determine whether or not your speaker is functioning correctly, you should try plugging it into a different device. 

  • Open the Windows search bar and search for “Sound Settings.”
  • Now navigate to “Sound panel” and open it. 
  • In the “Playback” section right, click on your default speakers and click on “Test” from the file.

Check Internet Speed

Internet speed is another important factor that can cause this audio issue. If you are using a slow and unreliable connection, then it is obvious that your audio will be cut out. However, the internet is used for audio and video in Zoom meetings, so the internet speed should be reliable. 

You can check your internet speed using a free online testing service like Ookla or Fast.Com. The website will show your network’s current download and upload speeds. In addition, you can restart the TCP / IP stack to refresh your internet connection.

  • Open the start menu, search for “Command Prompt,” and run it as administrator. 
  • Now rewrite this command “netsh int ip reset” and press enter.

Note: If you are using a statically configured IP connection, this reset may change the IP, and you may face internet connection issues.

Update Drivers

Outdated audio drivers will be unable to receive and transfer audio signals smoothly, resulting in a break in the audio stream. Because of this, you need to check to see that all of the drivers on your computer are updated to the most recent version.

  • Launch “Device Manager” on your computer, and expand the “audio inputs and outputs” in the menu that appears. 
  • Simply right-click on the device you normally use and then select “Update Driver” from the menu that appears.

  • Select “Search automatically for driver,” then let Windows search for the most recent version. 
  • Windows will look for the most recent version online, and if it finds one, it will automatically install that version on your computer if one is available. 

Enable High-Performance Mode

In case you are using a laptop that has different battery power modes. You may have inadvertently changed the mode to “Battery saver” or “Balanced,” neither of which will provide the audio device with the necessary power.

Therefore, you need to change it to “High performance” mode. The high-performance mode will give the audio device adequate power to function appropriately. It can also be done on desktop PCs having mini motherboards.

  • Go to the Start menu, search “Choose Power plan,” and open the settings.
  • Here, select the “Change plan settings” option.
  • In the newly popped-up windows, select “Change Advanced Power Settings.”

  • Go to the start menu, search “Services,” and open them. 
  • Now search for “Windows Audio Service” and “Windows Audio Endpoint Builder.”
