The feature will be useful in situations when people forget to mute themselves during meetings and thus, will ensure smooth running of video calls. Google Meet lets hosts mute others: How can you do it? This will allow them to have an interruption-free virtual meeting and restrict people from unmuting themselves unless they are unlocked by the hosts. Popular video-conferencing platform Google Meet has introduced a new Audio Video Lock feature that will allow hosts of a meeting to mute other participants.
