People cannot hear me on MS Teams

Dear @Pau,

I hope you’re having a good day and thank you for your question.

From what you described (you can hear and see others, and they can see you, but not hear you), this usually means the connection itself is working fine, and the issue is specifically with how the microphone is being picked up.

Even if the microphone is turned on in your privacy settings, it’s still possible that Teams is either using a different microphone or not receiving any input from the one you’re speaking into.

1. What I’d suggest is taking a closer look directly inside Teams. If you open Teams > Settings (or press Ctrl + Shift + ,) > Devices, you’ll see which microphone is currently selected. Try switching it to another available option (for example, if you have both a built‑in mic and a headset), and while you speak, watch the small input level bar, if it moves, that means Teams is detecting your voice. If it stays flat, then Teams isn’t receiving any audio from that device.

There’s also a ‘Make a test call’ option in Teams Settings, which can be helpful, it lets you record your voice and play it back immediately, so you can confirm whether Teams is actually picking up your microphone.

2. It’s also worth quickly testing the microphone outside of Teams, for example with your system’s voice recorder. If your voice isn’t picked up there either, that points to a system or hardware issue rather than something specific to Teams.
3. Another simple check is whether the microphone might be muted somewhere else, sometimes on a headset, keyboard button, or at the system level, or temporarily in use by another app in the background.
4. If you have access to Teams on your phone, it can also help to try a quick call there. If your audio works fine on mobile, that usually confirms the issue is limited to your computer’s microphone setup. If the same problem happens on mobile as well, then it may be something related to your account or device configuration more broadly.

In most cases like this, it turns out to be just a mismatch between the selected microphone and the one actually in use, even though permissions are already enabled.

If you’re able to check which microphone Teams is using and whether it detects your voice, feel free to share what you see, I’ll be happy to help you narrow it down further

Follow these steps to fix the microphone issue in Microsoft Teams:

1. Confirm Teams and OS are updated

• Install the latest Microsoft Teams update and the latest Windows or macOS updates, as outdated software can cause audio issues.

2. Make sure you are not muted

• In the meeting toolbar, check the Mic icon.
• If it has a line through it, select it to unmute.
• Also check any physical mute switch on your headset, external mic, or keyboard.

3. Check device privacy settings for the microphone

On Windows:

1. Open Settings > Privacy & security.
2. Select Microphone under App permissions.
3. Turn On:
   • Microphone access (or Microphone access for this device)
   • Let apps access your microphone (or Allow apps to access your microphone)
   • Microsoft Teams (work or school)
   • Let desktop apps access your microphone (or Allow desktop apps to access your microphone)
4. If these were already on, toggle them Off and then On again.
5. Close all apps and restart the device.

On macOS:

1. Open System Preferences.
2. Go to Security & Privacy > Microphone.
3. Ensure Microsoft Teams is checked.
4. Close all apps and restart the device.
5. Verify microphone selection in Teams

Before joining a meeting:

1. In Teams, select Settings and more (⋯) > Settings.
2. Go to Devices.
3. Under Audio settings, choose the correct device in the Microphone dropdown.
4. Select Make a test call and follow the Test Call Bot instructions. If the playback is silent or very low, change the microphone device and test again.

During a meeting:

1. In the meeting window, select the arrow next to the Mic icon.
2. Choose More audio settings.
3. Confirm the correct microphone is selected. If the device is missing, unplug and reconnect it (or disconnect/reconnect Bluetooth) and recheck the list.
4. Check browser permissions (if using Teams on the web)

Microsoft Edge:

1. Open Edge Settings > Cookies and site permissions > Microphone.
2. Turn on Ask before accessing (recommended).
3. When prompted by the browser while using Teams, choose Allow for microphone.

Google Chrome:

1. Open Chrome Settings > Privacy and security > Site settings > Permissions > Microphone.
2. At the top, select the correct microphone device.
3. Under Default behavior, select Sites can ask to use your microphone.

Safari (macOS):

1. In Safari, open Preferences > Websites.
2. Under Microphone, set When visiting other websites to Ask or Allow.
3. Restart the device.
4. If the mic still does not work in Windows

• Check and, if needed, update microphone/audio drivers via Device Manager as described in the Windows microphone permissions article.
• If using Bluetooth, ensure the headset is charged, not connected to another device, and reconnect it.

After completing these steps, run Make a test call in Teams again to confirm others will be able to hear.
