How Can I fix echoing audio during meetings?

Hi @mariacleh7 

Do you have more than one device connected to the meeting - like a laptop and desktop, or a laptop and mobile device? That might be one cause.

Or - one of your other participants may have open speakers, and an open (un-muted) microphone, and either their Echo Cancellation off, or their "Original Sound" ON. That would mean their microphone is picking up your voice and sending it back to you. But likely everyone else would hear an echo of themselves also. You could test for this by ensuring everyone else is muted, then see if you get the echo (with yourself un-muted).

Are other participants noticing an echo? How many participants do you have?

Or the other possibility is there is some sort of loop in your actual audio device locally. What are you using - built-in speakers/microphone, external headset, wireless anything?   

I use Zoom to broadcast our Sunday church services. I manage it remotely from my home. I have bought 2 sets of 2 lapel mount microphone for priests and lectors. In the past few weeks I have a horrible echo form the system in the church.  Any ideas on how to suppress the echo?

Same issue -- happening in one-on-one zoom meeting, where I hear my own voice echoing back, with about a one second delay. This happens with only this one person, who says this has not come up as an issue with any of her other one-on-one zooms. She also does not hear any echo (of herself or me). The echo also doesn't occur if I say one or two words, but does if it's a longer phrase / whole sentence. The only mitigant that seems to work -- but just a little (the issue is still there, it just isn't as bad) -- is lowering my computer speaker volume, and speaking softly. Issue occurs also when I use an external mic, and whether original sound is on or off. Tried having the other person go on mute, but the echo still occurred.

In my case, it turned out that this was occurring only when the other person was doing a screen share. We tried just about everything (including various suggestions from online searches). Finally, it was solved by disabling sharing of audio -- there's a box on the lower left corner of the share screen page. (While I was trying to solve the issue, I was told from various tech types that your hearing the echo of yourself likely relates to the other person's system -- it is picking up your audio and not properly processing noise cancellation and so it sends your voice back to you. I'm guessing in my case, the share audio feature had some additional driver enabled that was not properly processing the voice and canceling it -- it was inappropriately processing it as audio coming from its side and transmitting it back to you. Perhaps test with the person using a different device, say a laptop instead of cellphone??)  I hope you get your situation fixed -- hearing the echo drove me crazy, and this problem did not want to be solved.
