The most common cause of echo is the absence of a headset or a headset of poor quality. In such cases, the sound from the computer speakers (and sometimes even from headphones) gets into the microphone and is broadcast to the interlocutor, which causes an unpleasant effect.
Step 1. In order to prevent the occurrence of echo, it is recommended to use good quality headphones and a separate microphone.
Step 2. Make sure that you have only one virtual classroom tab open. If there are several of them, close the extra ones, leaving only one active one.
Step 3. Also make sure that you have closed other browsers on all devices (for example, connected from a mobile browser and switched to the application). The echo occurs when entering from two different devices at the same time.
Have a great lessons! 😃
