Fix Teams Speaker Audio Is Silent in Microsoft Edge

When you join a Teams meeting in Microsoft Edge, the speaker audio may remain silent even though the meeting appears connected. This issue occurs because Edge blocks autoplay for audio in web apps, or because Teams selects the wrong output device. In this article, you will learn the exact settings to change in Edge and in Teams to restore speaker sound.

The root cause is usually the Edge autoplay policy, which prevents Teams from starting audio output without a user gesture. Another common cause is that Windows sets the default playback device to a device that is not your speaker, such as a headset or a virtual audio cable. You will also find fixes for related symptoms like audio cutting out or being too quiet.

Why Teams Speaker Audio Is Silent in Microsoft Edge

Microsoft Edge has a media autoplay policy that blocks websites from playing audio automatically. This policy is designed to prevent unexpected sounds from playing when you open a page. However, Teams relies on autoplay to output audio when a meeting starts. If Edge blocks autoplay, the meeting connects but the speaker remains silent.

Another cause is the audio device selection. Teams in the browser uses the default playback device that Windows has set. If that default is a Bluetooth headset that is off, or a virtual cable that is not connected, you hear nothing. The Teams web app also has its own device settings that can override the Windows default.

A third cause is the volume mixer in Windows. Edge and Teams each have separate volume sliders. If the Edge slider is low or muted, you will not hear any audio even if the system volume is high. The mixer can be changed by other applications, so it is worth checking after every update.

Steps to Fix Silent Speaker Audio in Teams on Edge

Follow these steps in order. Test the audio after each step to identify the exact cause.

Step 1: Allow Autoplay in Edge

1. Open Edge settings
   In the Edge address bar, type edge://settings/content/mediaAutoplay and press Enter.
2. Change the autoplay setting
   Select Allow from the dropdown next to Control autoplay of audio and video.
3. Reload Teams
   Close the Teams tab and open it again. Join a test meeting or call to verify the speaker audio.

Step 2: Check the Windows Volume Mixer

1. Open the volume mixer
   Right-click the speaker icon in the Windows taskbar and select Open volume mixer.
2. Check Edge and Teams sliders
   Look for Microsoft Edge and Microsoft Teams in the list. Drag each slider to at least 80 percent. Click the speaker icon under each slider to unmute if it is muted.
3. Test the audio
   Play a sound in Teams and confirm the mixer shows the volume moving.

Step 3: Set the Correct Default Playback Device in Windows

1. Open sound settings
   Press Windows key + I to open Settings, then select System > Sound.
2. Choose the output device
   Under Output, select your speakers from the dropdown. If you have multiple devices, pick the one that is physically connected and powered on.
3. Test the sound
   Click Test next to the device name. If you hear a chime, the default device is correct.

Step 4: Select the Speaker in Teams

1. Open Teams settings
   In the Teams web app, click your profile picture at the top right, then select Settings.
2. Go to devices
   Select Devices from the left menu.
3. Set the speaker
   Under Speaker, choose the same device you set in Windows. Click Make a test call and follow the prompts to hear the test tone.

Step 5: Clear the Edge Cache and Site Data

1. Open Edge settings
   Type edge://settings/clearBrowserData in the address bar and press Enter.
2. Select time range
   Choose All time from the Time range dropdown.
3. Clear cached data
   Check Cached images and files and Cookies and other site data. Click Clear now.
4. Reload Teams
   Close the browser completely and reopen it. Sign in to Teams again and test the audio.

If Teams Audio Is Still Silent After the Main Fix

Teams Shows a Muted Speaker Icon in the Meeting

The meeting controls may have the speaker muted. Click the speaker icon in the meeting toolbar to unmute it. This setting is separate from the device settings and can be toggled accidentally.

Audio Is Silent Only for Other Participants

If you hear the test tone but not other people, the issue is likely with the incoming audio stream. Ask the presenter to check their microphone. Also verify that the meeting is not in a channel where the presenter has muted all participants.

Edge Uses the Wrong Audio Device After a Bluetooth Connection

When you connect a Bluetooth headset, Windows may switch the default device. Disconnect the headset and repeat Step 3 to set your speakers as the default. Then in Teams, repeat Step 4 to select the speaker again.

Audio Works in the Desktop App but Not in Edge

This confirms the issue is specific to Edge settings. Check the autoplay policy again and ensure the site permission for Teams is set to Allow. Also disable any extensions that block media, such as ad blockers.

New Teams Desktop vs Teams on Edge for Audio Reliability

Item	Teams Desktop App	Teams on Edge
Autoplay policy	Not affected by browser autoplay	Blocked by Edge unless allowed
Device selection	Uses Windows default plus in-app override	Uses Windows default plus in-app override
Volume mixer integration	Separate app entry in mixer	Shares Edge entry in mixer
Common silent audio cause	Wrong device selected in app	Autoplay blocked or Edge mixer muted

After applying the fixes above, you should hear speaker audio in Teams meetings within Edge. Start with the autoplay setting because it is the most common cause. Then verify the Windows default device and the Teams speaker selection. If audio still fails, use the Teams desktop app as a fallback, and report the issue to your IT admin if the problem persists across all devices.
