Echo in video calls is often caused by external factors, here are some tips that can help you prevent any video call anomalies:
✅ If you are using external speakers, place the speakers away from the laptop microphone and turn down the volume to a comfortable level.
✅ For those who have external microphones, move the microphone about a foot away from the speakers. Avoid typing on an unmuted microphone, and step back from the laptop when using hands-free mode. You can also reduce the microphone volume level by 50% or less and reduce or turn off the microphone boost option.
✅ Some computers have an echo cancellation feature, but it could be compromised on high CPU load. Closing few processes will help enable that feature.
✅ If none of these options are successful, use a headset or headphones instead of speakers. This is the easiest way to get rid of an echo.
