I am using teams from chrome browser and the person on the other side hears echo when they speak. Please help.

I can confirm the same echo related issue on any chromium browser (chrome, edge, brave). What I have discovered is that the cancellation appears to be established at the start of a call. If you have background noise then you are more than likely going to have the issue where your teams connection results in everyone else hearing echo of themselves. For myself this started around 16/17 Jan 2024. Changing the Noise Cancellation between Auto, High, Low, Medium on my M1 does not have any real effect on the problem. Extensive testing over a number of hours to get this far as the echo almost makes teams unusable. I have had a great deal of success with Safari not having the echo problems however it does appear to have video problems. I suppose i could try changing the user agent and see if that addresses anything.

In short, it appears the AI cancellation is messed up and Teams on Chromium is only usable if your in a dead silent room otherwise the cancellation causes echo for other parties.

I hope this gets fixed earlier rather than later.

Same issue, last week echo started out of nowhere, nothing about the computer changed

Echo does NOT happen in the teams app, so something about the web version.

Happens in both "new teams" and "old teams" in the browser.

The problem does seem to have been caused by a recent update. And it's not isolated to Mac users. I am using a PC and have been experiencing this issue since last week. This issue seems to have started at the same time that my Office products were "updated" with new visuals and color themes (the dark gray theme is now horrible, btw). So perhaps something to do with a MS Office update?

Also having the same problem. For some further context: I am on a 12 person team where one other person is having this issue, the only other person using Teams on a Mac. It happens across browsers, after turning everything off and on, after ensuring we have selected the right microphone, and after closing all other tabs. It can only be dealt with by using headphones, which is incredibly frustrating. Only began happening after coming back after the holidays, so we suspect that an update caused this issue.

Yes, I have tried this, but that setting does not appear in my options.

I see. Looks like option depends on browser/OS. In MacOS, I see it in Edge and Chrome, but not in Safari.

It seems to improve the call quality a bit, but some users are still complaining about echo; Safari is also affected. Desktop app is the only one which works with no echo issue.

So, fix will be required for the web version, since it seems to be a software issue introduced around January 10, and echo cancellation is not working anymore.
