Echo and Feedback

Sometimes you will hear audio echo or audio feedback during your meeting. For bigger groups, it is advisable to select "Mute Participants on Entry". For even larger groups, you may want to prevent students from unmuting themselves.


To solve the Echo issues:

1) Isolate the participant
As a host, if it is a small group, you can do a Mute All and unmute individually to find the source. You might not have a time to do this in a big group. Do a Mute All and let them know to unmute only when given permission to talk.

2) Cause of Echo

• Participants not joining using headsets and joining using external speakers. So what happens is the built-in mic picks up audio from the external speakers causing echo from other.
  Unfortunately, in most cases the one causing echo will not hear the echo.
• Two or more participants with active audio joining from the same room (physically). If that is the case, only one device should Join Audio. All other devices should Leave Audio.
