There are three possible reasons for hearing audio echo or feedback during your meeting:
- Audio is active on both the computer and the telephone for a participant.
- Participants have speakers too close to each other on the computer or the telephone.
- Multiple computers are in the same conference room with active audio.
It is also possible to hear echo from speakers (such as TVs or soundbars) that are too loud, failed echo cancellation (device or performance issue), or a bad microphoWhen you hear an echo, it usually means that something is channeling back your audio.ack.
The following steps can be taken to isolate the attendee:
- Each attendee can be muted individually by the host.
- Muting all and unmuting one at a time is possible by the host.
- Attendees can also mute themselves.
Prerequisites for managing the audio echo in a meeting
- Zoom desktop client
- Windows: 5.2.1 or higher
- macOS: 5.2.1 or higher
- Linux: 5.2.1 or higher

Case 1: Both the computer and telephone audio are active
If you join from a computer and call in from the telephone, ensure that you follow the steps below:

- Enter your participant ID followed by #when calling in to a meeting or webinar.
- (Optional) Enter your #participant ID# when you’re already in the call.
- (Optional) Manually leave computer audio on your computer.
Case 2: Computer or telephones speakers are too close to each other
Keep the audio conference on one of the computers or disconnect the telephone connections if another participant is too close and both of you have speakers on.
Case 3: Multiple computers with active audio are in the same conference room
Separate the computer audio from other devices if you are in a conference room with multiple devices. See Joining a meeting or webinar by phone for more information about disconnecting computer audio.
It’s not enough to mute the mic since the speaker is still on even if the mic is muted.
