The local audience should be listening to the in-room audio, in order to avoid echo. Also, all local mics should be muted, if someone is speaking from a remote location. Yet, echo is unavoidable if a remote participant is speaking while listening to the audio without headphones. If this ever happens, I guess the moderator should cut the remote audio and ask the remote participant to lower their speakers or use a headphone. Thanks, Mauro
