Microsoft Teams Others Hear Echo

Not much help but I also have experienced this when using TeamViewer and other similar apps. The reason I was experiencing this was because of the builtin speakers and mic. If someone on the call has the builtin speakers and mic active then the speaker sound when you talk is picked up by their mic then the mic causes the speakers to repeat the picked up sound (echo).

Microsoft Teams has a macOS version, which can be installed for testing purposes. I use it and use an external phone or built-in Microphone/Speakers, depending on what is handy. On the non-working Macs, install Teams on the macOS side, and re-run your test using the same environment as Bootcamp and check.

I also have W10 (dual-boot Bootcamp), that I can try to test in the next couple of days, when the opportunity arises.

I do not have a 2019 MBP, but a 2018 model.

Yes same issue with me also. MS teams is behaving really weird on boot-camp windows. Apple please provide a fix,

The issue is delay and picking up remote and system mic sounds. The solution as it is with all such remote apps is to use a headphone and external mic. This prevents your internal mic from picking up the remote user's voice/sound and capturing it then feeeding it back. All devices perform this way. Think of it. The remote user speaks 1000miles away., your computer plays his voice a few milliseconds later (it takes time for electric signal to travel 1000miles). Your built in mic pics up his voice when you hear it and plays it back to the original speaker 1000miles away. Again there is a few milliseconds delay. Hence the echo when using the built in mic. Use earphones so that his voice can not be picked up by your internal mic. Everyone on the call needs to use a headset and external mic for best sound quality and no feedback (echo).

This echo issue is when you join by laptop audio

If you have this issue, have you considered recalibrating your microphone? Ambient noise cancellation (including speaker feedback) can typically be compensated for. I had to do the same on both macOS and Windows, otherwise I used to get feedback.

Now we are getting the dreaded "robot voice" instead.

I typically create a Windows System Restore point, before I apply any Windows Updates and/or Apple Software Updates to Windows. Otherwise I end up with really bad drivers.

I have the BC/Windows version of Teams in use for the last month. If I use my phone for audio, I have to mute the built-in Audio Input/Output. I have tested with a TRRS headset (which is not that great). Built-in Audio works fine, if I do not have a phone handy. I can also use the Teams app on the phone. I have also tested with Apple AirPods connecting to both MacOS and Windows for Teams, which works fine.

If you can provide more details of your configuration, I can test the configuration that is causing issues for you.

Yes the only fix is to leave and rejoin. I look very silly doing that every 30 minutes. Eventually people take my leaving as the time marker to keep track of the meeting duration.

Can't believe before this, there's not many post on this issue. Was wondering how people cope with this?

Why do you think all the tv reporters wear a headset when they are streaming? It is the nature of using a speaker and open mic. You speak and your built-in mic picks up your voice. Your voice is transmitted to the remote computer where that computer's speaker broadcasts your voice. That computer's built in mic picks up your voice broadcast by that computer's speaker. That computer then broadcasts your voice it just picked up and you hear it as an echo.

Get a headset so that sound is not broadcast such that the computer's mic can pick it up and rebroadcast it.

I’ve been having this exact same issue. I have a 2019 MacBook Pro. All system updates, OS, and application updates are up-to-date. Works for 30min, then issues. The only thing that seems to work is dialing into Teams calls from my iPhone, while then doing another hard shutdown and start up on the Mac to reset. Tried resetting PRAM and SMC, no luck. Makes it ****** hard to get work done.

Loner T, issue will occur when you join MS teams audio with macbook pro. There is an option to join by phone or use laptop audio/microphone. This echo issue is when you join by laptop audio

This (Echo and Robot) has been happening all on 2019 MBPs.

Does this happen in both versions of Teams - macOS and Windows?

For users who hear the echo, what is the setting for the Speaker volume?

See Mic issue on Windows 10 bootcamp - Apple Community , which is Crusaderdotcom's original discussion.

I have a 2018 MBP with T2, but I bought a refurbished unit from Apple and do not see such issues. Let me keep an eye out when I use Teams next. My primary audio device is a phone+headset, video comes through the laptop.
