Quick launch summary 

We’re making it easier to identify and fix when an echo is happening in Google Meet video calls. ‘Echo’ can happen when your system feeds back audio into a call. Most of the time, Meet will intelligently control the audio to remove the echo. However, sometimes it still happens and causes others to hear an echo from your device when they speak. Until now, it has been difficult for you to know when your device is causing an echo. Now, we will notify you when we detect a notable echo from your system which may be heard by other call participants with a red dot on the more options button, along with a text notification. Clicking on the notification will go to our Help Center, where you can find recommended steps that can help prevent echo. 

Users may see a notification alerting them when they’re causing an echo 

If you click on the notification, there are troubleshooting steps you can take which might help reduce the echo
