    Hi @Calvin Ting

    Thank you for sharing the issue. To better understand what is causing the echo, could you please confirm the following:

    • Are you using the Teams desktop app, Teams on the web, or a mobile device?
    • Does the echo happen in every meeting or only in a specific meeting?
    • Are you using a headset, external speakers, or the device’s built-in microphone and speakers?
    • Are multiple devices joining the meeting from the same room?
    • When you select the three-dot menu, is Settings missing, greyed out, or does the menu not open at all?
    • Could you please test the same Teams meeting using a different headset, microphone, or device and let us know whether the echo still occurs?

    If possible, please also share a screenshot of the three-dot menu, making sure to hide any personal information.

    If the echo occurs only with one particular headset, microphone, or speaker but disappears with another device on the same computer, the issue is more likely related to that audio device, its driver, or its configuration.

    If the same device works normally in Teams on the web or in another application, but the echo occurs only in the Teams desktop app, please first fully quit and restart Teams and check for updates. If the issue continues, clearing the Teams cache may help with a local client issue. Reinstalling Teams can then be considered if clearing the cache does not resolve it.

    I’m just another community user, not a Microsoft employee, but these details will help narrow down whether the issue is related to the audio setup, the Teams app, or the meeting environment.

    Use only the Teams Room’s microphone and speakers, and turn off audio on every laptop, tablet, or phone that joined the meeting from the same classroom.

    Stop the echo immediately

    1. On each personal device in the room, select Mic → Mute, then turn its speaker off or choose Audio off.
    2. Leave the Teams Room microphone and speakers active.
    3. If someone must rejoin from a laptop:
      • On the pre-join screen, select Room audio to use the classroom system; or
      • Select Don’t use audio/Join without audio if the Teams Room is already connected.

    Microsoft specifically warns that keeping personal-device audio active while accepting the call on a Teams Room can cause echo.^1^

    The missing Device settings option is not something that must be corrected from the meeting’s three-dot menu. Teams Rooms use their room console and administrator controls rather than the standard desktop meeting settings. The room console still provides microphone, camera, volume, and other meeting controls.^2^

    If echo remains with only the room audio active

    Ask the school’s IT or classroom-device administrator to identify whether the room runs Teams Rooms on Windows or Teams Rooms on Android.

    Teams Rooms on Windows

    A documented cause of echo sent to remote participants is the Windows audio-enhancement setting on an attached Teams-certified USB audio device. An administrator should:

    1. On the room console, select Settings → Windows Settings.
    2. Sign in as an administrator.
    3. Open Control Panel → Hardware and Sound → Sound.
    4. On the Playback tab, select the room audio device and choose Properties.
    5. Open Advanced.
    6. Under Signal Enhancements, clear Enable audio enhancements, then select OK.
    7. Repeat the same change for that device on the Recording tab.
    8. Close Control Panel and restart the Teams Room.

    This is Microsoft’s published workaround for Teams Rooms on Windows devices producing echo or poor USB audio.^3^

    If the room uses a certified digital signal processor (DSP), Teams Rooms automatically relies on that DSP for acoustic echo cancellation. The administrator should therefore check the DSP and microphone manufacturer’s configuration rather than trying to enable a desktop Teams noise-suppression option.^4^

    Teams Rooms on Android

    Noise suppression and other audio processing are controlled by the device manufacturer and its firmware; the Teams Rooms Android app does not provide Teams-client-based noise suppression. The administrator should check the OEM management interface, firmware, microphone placement, and manufacturer support guidance.^4^

    If multiple room systems join together

    If the classroom intentionally uses multiple Teams Rooms devices or a Teams Room with a Surface Hub, the administrator should configure Coordinated meeting join so only the designated device supplies audio. This feature coordinates audio and video to prevent echo and is supported only on Teams Rooms on Windows.^5^
