Does the host need their volume set lower to avoid the echos, or should all attendees have their volume reduced?

Hi, I just muted all participants one by one and this did not resolve the issue. Playing around with my audio settings, I identified that when my local playback is set differently than where Teams is steering the audio (i.e. computer audio to speakers and Teams to headset the echo is gone), it seems that there audio is fed-back into the same channel on the computer when both the computer and teams are using the same audio endpoint.

Hi Arjo Kalisvaart,

Thank you for sharing what you’ve observed, this is a helpful clue.

What you’re describing is a different echo scenario than the usual “someone’s mic is picking up speaker audio in the room.” The “mute everyone one-by-one” test is great for finding that attendee‑side acoustic echo, and since it didn’t change anything in your case, it strongly points to a local audio loop on the host device instead.

To clarifying the two common echo types:

Acoustic echo (most common): sound plays from speakers → microphone hears it → echo. Typical fixes are lowering speaker volume, using a headset, and ensuring only one device in a room has mic/speakers active.

Digital “loopback” echo (what your note suggests): when Teams and the OS are using the same endpoint, some audio drivers/devices can route (“monitor”) the playback stream back into the capture stream. This can create echo even if no one else is unmuted. Your workaround (system audio to speakers, Teams to headset) likely breaks that internal routing path, which is why the echo disappears.

Since splitting the endpoints removes the echo for you, the most effective approaches are:

Keep Teams audio fully on one device (speaker + mic) and keep OS/system audio on another device (as you tested), or

Try a different headset / audio endpoint (USB vs Bluetooth vs built‑in), because the behavior can be device/driver specific. (Suggestion based on common troubleshooting practice; not a Teams-only setting.)

If you ever switch back to a single endpoint, the “classic” mitigations still apply (headset, volume, distance from reflective surfaces), but in loopback cases the device/driver choice is usually the deciding factor.

Hello Tom Levenick,

Thank you for reaching out in the Microsoft Q&A forum.

I understand that you are experiencing persistent echoing while hosting Microsoft Teams meetings, and I appreciate how distracting this can be.

I noticed that Q&A Assist has already suggested several common fixes, such as using headphones and lowering volume levels. These are standard first steps, and I recommend you try them. I would also like to address your specific question about whether the host or attendees need to lower their volume.

To narrow this down, it helps to identify who is hearing the echo:

If you (the host) hear an echo of your own voice, the issue is usually caused by an attendee's microphone picking up your voice from their speakers.
If attendees hear an echo of their own voices, the issue is likely coming from your (the host's) setup.

Here are some tailored methods to resolve this incident:

1, Identify the Source (The Mute Test)

The fastest way to stop an echo is to find out which device is leaking sound:

Ask all participants to mute themselves.
Have them unmute one by one while you speak.
When the echo returns, that specific participant should lower their speaker volume or switch to a headset.

2, Enable Noise Suppression

Teams has a built-in feature to help eliminate background echo. Ensure this is active in your settings:

In Teams, click the three dots (...) next to your profile picture and select Settings.
Select Devices.
Find the Noise suppression section and ensure the toggle is turned On.

3, Manage Multiple Devices in One Room

If multiple people are attending the meeting from the same physical room, a feedback loop is very common:

Only one person in the room should have their microphone and speakers active.
All other participants in that room must mute their microphones and turn their device volume all the way down.

Note: For the most reliable audio experience, I recommend using a headset, as it physically separates the speaker output from the microphone input.

I appreciate your patience while looking into this. I look forward to hearing from you.

Hello Tom Levenick,

I am following up to check whether you have had an opportunity to review the response provided and try the suggested steps.

Please feel free let me know if you need any further assistance. I remain available to assist you further.

To stop echoing during a Microsoft Teams meeting, you can follow these strategies:

Use Headphones: The quickest solution is to have participants who are producing echo use headphones. This prevents the microphone from picking up sound from the speakers, which is a common cause of echo.
Adjust Volume Levels: Lowering the speaker volume can help reduce echo. If the volume is too high, it may cause the microphone to pick up the sound, leading to echo.
Microphone Sensitivity: Adjusting the microphone's sensitivity can also mitigate echo issues. A lower sensitivity setting may help reduce the chances of the microphone picking up unwanted sounds.
Positioning of Speakers: If using external speakers, point them away from the microphone to minimize sound pickup.
Coordinated Meetings Setup: If you are using multiple devices in a meeting room, ensure that only one device has the microphone enabled. This helps avoid echo and feedback noise from multiple microphones being active at the same time.

By implementing these measures, you should be able to significantly reduce or eliminate echo during your Teams meetings.
