## Key takeaways

- Work in order, from mute and the physical switch to Windows privacy toggles, then the Windows input device, then the device chosen in Teams or Zoom.
- Desktop apps are controlled only by the Let desktop apps access your microphone toggle in Settings > Privacy & security > Microphone.
- Teams and Zoom each have their own microphone drop-down, so a working Windows input does not guarantee the app is using it.
- Windows has a built-in input test under Settings > System > Sound that shows whether the problem is the hardware or the app.
- Uninstalling the audio device in Device Manager and restarting lets Windows reinstall the driver and often clears detection problems.

When your microphone is silent in Teams or Zoom on Windows 11, work through four layers in order: the mute controls, the Windows privacy toggles, the input device Windows has selected, and the device chosen inside the app. Most cases are fixed by turning on **Let desktop apps access your microphone** or by picking the right microphone in the app's own audio settings.

## Who this is for and what you will have at the end

This guide is for Windows 11 users whose microphone is not picked up in Microsoft Teams or Zoom, whether it is a laptop mic, a USB headset or a Bluetooth headset. At the end you will know whether the fault is the hardware, Windows or the app, and you will have a working input confirmed by a test recording.

You do not need administrator rights for most steps. Uninstalling an audio driver in Device Manager may need them on a work PC, and on a managed device an IT policy can lock some settings.

## Step 1: Rule out mute and hardware

Do these first, because they take under a minute.

1. In the meeting controls, look at the **Mic** icon. In Teams, if it has a line through it, select **Unmute mic**. In Zoom, click the muted audio icon to unmute. In Zoom, if you still cannot unmute, the host may have muted you; send them a chat message.
2. Check for a physical mute button or switch on the headset or external microphone. Microsoft's page lists this as a common cause for "others can't hear me".
3. If the headset has a boom microphone, make sure it is positioned near your mouth.
4. Make sure the cable is fully inserted. If Zoom does not detect the microphone, unplug it and plug it back in.
5. For a wireless headset, confirm it is on, charged and connected. Teams guidance adds that a Bluetooth microphone should not be connected to another device at the same time. If Bluetooth is the issue, see our guide to [Bluetooth not working on Windows 11](https://www.epifive.com/blog/windows-11-bluetooth-not-working-fix).

If you recently updated Teams or Windows, install any pending updates and restart. Microsoft's Teams troubleshooting begins with updating Teams and the operating system.

## Step 2: Check the Windows microphone privacy settings

Windows can block microphone access for all apps or for desktop apps specifically. This is the most common cause when the microphone works in one place but not in another.

1. Open **Start > Settings > Privacy & security > Microphone**.
2. Turn on **Microphone access**.
3. Turn on **Let apps access your microphone**.
4. Scroll down and turn on **Let desktop apps access your microphone**.

Microsoft notes that desktop apps do not appear in the list of apps on this page, and that the desktop toggle is the way to allow them. You cannot turn off microphone access for individual desktop apps, so there is no separate switch for Zoom or classic desktop clients.

For Teams, the Microsoft article also lists **Microsoft Teams (work or school)** in this list. Make sure it is on. If every toggle is already on, turn them off and on again, close all apps and restart the PC, which is Microsoft's own suggestion.

If your microphone is built into a webcam, also check **Start > Settings > Privacy & security > Camera** and confirm **Camera** access is on, as Microsoft's page directs.

## Step 3: Check the input device in Windows

Even with permission granted, Windows may be sending audio from the wrong device, such as a monitor with a microphone or a disconnected headset.

1. Open **Start > Settings > System > Sound**.
2. Under **Input**, choose your microphone in **Choose a device for speaking or recording**.
3. Select the arrow next to the device to open its properties.
4. Under **Microphone test** (or **Input settings**, depending on the build), select **Start test**, speak normally, select **Stop test**, then under **Recorded sample** select **Play**.
5. If playback is silent or very quiet, raise the **Input volume** slider and test again.

This test is the dividing line. If the recording works here, the hardware and Windows are fine and the problem is in the app. If it does not work, continue with the Windows fixes below before changing anything in Teams or Zoom.

If the microphone does not appear in the list, select **Add device** to pair a Bluetooth microphone, as the Teams article suggests.

### Enable the device in the classic Sound panel

If problems persist, go to **Advanced > More sound settings** on the Sound page. On the **Recording** tab, right-click your microphone and select **Enable** if it is disabled. This step comes from Microsoft's Teams guidance.

### Run the Windows audio troubleshooter

On **Settings > System > Sound**, scroll to **Advanced** and select **Input devices** under **Troubleshoot common sound problems**. Select **All sound devices** under Advanced for more options. Follow the prompts and test again.

## Step 4: Choose the microphone inside Teams or Zoom

Each app keeps its own device selection, so a correct Windows input does not guarantee the app is using it.

### Microsoft Teams

Before a meeting:

1. Select **Settings and more** (the three dots) **> Settings > Devices**.
2. Under **Audio settings**, choose your microphone from the **Microphone** drop-down.
3. Optionally select **Make a test call** to try it. Microsoft notes the test call is English-only and not available in Teams on the web.

During a meeting, select the drop-down arrow next to **Mic**, then **More audio settings**, and choose the right microphone. If the microphone is not in the list, unplug it and plug it back in.

### Zoom

1. Sign in to the Zoom desktop app, click your profile picture, then click **Settings**.
2. Open the **Audio** tab.
3. Under **Microphone**, test the microphone, select the one you want from the drop-down and adjust the **Input Volume** slider.
4. Optionally, open the advanced audio settings and turn off **Signal processing by Windows audio device drivers**. Zoom lists this as something to try; change it only if you have audio problems, and note what it was before so you can restore it.

To switch microphones mid-meeting, click the up arrow next to **Mute** on the toolbar and pick another device. Zoom's guidance for Bluetooth headphones is to select the headphones for both microphone and speaker, then join a test meeting to confirm.

### Teams or Zoom in a web browser

If you use Teams or Zoom in a web browser, the browser needs permission too. Microsoft's article gives these paths:

| Browser | Path |
|---|---|
| Edge | Settings and more > Settings > Cookies and site permissions > Microphone, then turn on **Ask before accessing (recommended)** |
| Chrome | Settings > Privacy and security > Site settings > Permissions > Microphone, confirm the device, and under **Default behavior** select **Sites can ask to use your microphone** |

Some settings may be locked by your IT administrator.

## Step 5: Fix driver and detection problems

If Windows does not see the microphone at all, or it vanishes after an update, reset its driver. This procedure is from Microsoft's "Fix microphone problems" page.

1. Right-click **Start** and select **Device Manager**.
2. Expand **Sound, video and game controllers**.
3. Right-click each audio device, select **Uninstall device**, tick **Attempt to remove the driver for this device**, and select **Uninstall**. Repeat for the other audio devices.
4. Restart the PC. Windows should reinstall the devices automatically.
5. If it does not, open Device Manager, right-click **Sound, video and game controllers** and select **Scan for hardware changes**.
6. To update rather than reinstall, right-click your audio driver and select **Update driver**.

Be careful on a work laptop: the audio driver may be supplied by the manufacturer or by your IT team, and removing it could leave you without sound until it is reinstalled. If you are unsure, ask your IT team first.

## Step 6: Remote Desktop and virtual machines

If you join meetings from a remote Windows session, the microphone on your local PC has to be passed through. In **Remote Desktop Connection**, go to the **Local Resources** tab, select **Settings** under **Remote audio**, set **Remote audio playback** to **Play on this computer** and **Remote audio recording** to **Record from this computer**, then select **OK**. Microsoft also notes that Teams in a virtual desktop may need an optimized setup; that is an administrator topic.

## Last resort: use your phone for audio

If a Teams meeting shows a **Call me back** option, you can select it, enter your phone number and select **Call me**. Audio then comes from your phone while you keep sharing content from the PC. This is a stopgap to get through the meeting, not a fix.

## Quick diagnosis table

| Symptom | Most likely cause | Fix |
|---|---|---|
| Works in Windows test, silent in app | Wrong device selected in app | Step 4 |
| Silent in Windows test | Privacy, driver or hardware | Steps 2, 3 and 5 |
| Fine until a Windows update | Privacy toggles reset or driver changed | Steps 2 and 5 |
| Bluetooth headset connected, no one hears you | Headset set as speaker only, or connected elsewhere | Steps 1 and 4 |
| Desktop apps blocked but browser works | Desktop apps toggle is off | Step 2 |

## Verify the fix

1. Run the Windows input test and confirm the recorded sample plays back clearly.
2. In Teams, use **Make a test call**. In Zoom, use the Audio tab test or join a test meeting.
3. Ask a colleague to join a short call and confirm they hear you at a normal volume.

If you work from home often, it also helps to have a reliable network. Our guide on [fixing Wi-Fi problems on Windows 11](https://www.epifive.com/blog/wifi-not-working-windows-11-fix) covers the common causes of choppy calls.

## Frequently asked questions

### Why does my microphone work in Windows but not in Teams or Zoom?

Usually the app is using a different input device than the one Windows is using, or Windows privacy settings are blocking the app. Check Settings > Privacy & security > Microphone, then choose the microphone explicitly in the Teams or Zoom audio settings.

### Why is "Let desktop apps access your microphone" important?

Desktop apps such as the Teams and Zoom desktop clients do not appear in the list of apps under the microphone privacy setting. Microsoft says the Let desktop apps access your microphone toggle is the only way to allow them, and it must be on.

### How do I test my microphone in Windows 11?

Go to Start > Settings > System > Sound, select your device under Input, and under Input settings select Start test. Speak, select Stop test, then select Play to hear the recorded sample. Adjust the Input volume slider if it is too quiet.

### My Bluetooth headset connects but nobody hears me. What should I check?

Confirm the headset's own mute button is off, that it is charged and not connected to another device, and that it is selected as the microphone, not just as the speaker, in Teams or Zoom. Microsoft and Zoom both advise selecting the headset for microphone and speaker separately.
