Answer 1

Good day Kyle,

Just to gently clarify before going any further, this forum is separate from Microsoft Support. I don’t have the ability to access or investigate individual accounts because this is a user‑to‑user support forum.

To help me better understand the situation and assist you effectively, could you please share a few details such as:

1/ Are you using the Teams desktop app or Teams on the web?

2/ Is your device running Windows or macOS?

3/ Does the microphone work normally in other apps such as Zoom or Google Meet?

4/ Did you join the meeting from your laptop or your phone?

This will help me better understand the context and provide more targeted support. Any additional information will help me better understand and support you.

In the meantime, if you're using a Windows device, please try the steps below in order:

Note: You can also try the additional troubleshooting steps in the AI Answer.

Step 1: Try use Teams on the web

If you're experiencing the issue in the Teams desktop app, please try joining the meeting using Teams on the web. You can also go to Settings and more (three-dot icon) > Settings > Devices and select Make a test call to test your microphone.

Step 2: Check for updates

Please update Teams and Windows, then install the latest Bluetooth and audio drivers from your computer manufacturer. If your earbuds have a USB dongle, try using it instead of the computer's built-in Bluetooth connection.

Step 3: Check the microphone in Teams

In the meeting, make sure your microphone isn't muted in Teams. If your earbuds have a mute button or microphone boom, check that it isn't in the mute position.
Select the arrow next to the microphone icon and open Audio settings.
Under Microphone, select the microphone you want to use.
Speak and confirm that the microphone level moves.
You can also go to Settings and more (three-dots icon) > Settings > Devices and run Make a test call to test the microphone.

Step 4: Reconnect the Bluetooth earbuds

Make sure the earbuds are charged and disconnected from other devices. Remove and pair them with Windows again, then go back to Teams > Settings > Devices and select the earbuds for both Speaker and Microphone.
If the microphone still doesn't work, try using the computer's built-in microphone while keeping the Bluetooth earbuds selected as the speaker.

Step 5: Reinstall Teams app

If the issue continues, uninstall Microsoft Teams from Windows Settings > Apps > Installed apps, then restart your computer. Download and install Teams again, sign in, and go to Settings > Devices to select the correct speaker and microphone. After that, make a test call to check the microphone again.

If you have any questions, please don’t hesitate to reach out at any time.

Thank you for your patience and understanding.

Answer 2

Because the laptop microphone also fails at the Windows level, restore microphone input in Windows first, then select and test the recovered microphone in Teams.

1. Enable microphone access

Use the path matching your Windows version:

Windows 11: Start → Settings → Privacy & security → Microphone
Windows 10: Start → Settings → Privacy → Microphone

Turn on:

Microphone access or Allow apps to access your microphone
Let apps access your microphone
Let desktop apps access your microphone

For Windows 11, also enable Microsoft Teams (work or school) if it is listed. Close Teams after changing these settings. ^1^

2. Test the microphone directly in Windows

This determines whether the remaining problem is Windows/hardware or Teams.

Windows 11

Open Settings → System → Sound.
Under Input, select the laptop microphone.
Select Start test, speak normally, and then select Stop test → Play.
Increase Input volume if the recording is very quiet.

Windows 10

Open Settings → System → Sound.
Under Input, select the microphone in Choose your input device.
Speak and watch Test your microphone.
If necessary, open Device properties → Levels and increase Microphone and Microphone Boost.

If the meter or recording responds, continue to the Teams section. If it does not, continue below. ^2^

3. Enable a hidden or disabled recording device

Open Settings → System → Sound → More sound settings.
Select the Recording tab.
If the microphone is missing, right-click an empty white area and enable:
- Show Disabled Devices
- Show Disconnected Devices
Right-click the microphone that appears and select Enable.
Return to Windows Sound settings and test it again. ^3^

4. Select the recovered microphone in Teams

After Windows successfully records sound:

Open Teams.
Select Settings and more (…) → Settings → Devices.
Under Audio settings, select the required device in Microphone:
- Choose the laptop microphone to test the built-in input.
- Choose the earbuds’ microphone to test Bluetooth input.
Select Make a test call, record a message, and listen to the playback. The test-call feature is available in the Teams desktop app on Windows and Mac. ^4^

If Windows still receives no microphone input

Reinstalling audio drivers removes the current audio-device driver temporarily, so save work and be prepared to restart:

Right-click Start → Device Manager.
Expand Sound, video and game controllers.
Right-click the audio device and select Uninstall device.
If offered, select Attempt to remove the driver for this device on Windows 11 or Delete the driver software for this device on Windows 10.
Restart the laptop. Windows should reinstall the audio device automatically.
If it does not, open Device Manager and select Action → Scan for hardware changes.
Test the microphone again.

If the built-in microphone remains undetected after driver recovery, install the audio driver supplied by the laptop manufacturer. Persistent failure may require a hardware inspection. ^2^

Bluetooth earbuds

Since earbud playback works, first resolve the Windows-wide microphone failure. If the laptop mic then works but the earbud mic does not:

Ensure the earbuds are charged and not connected to another phone or computer.
In Windows 11, open Settings → Bluetooth & devices → Devices, select the earbuds’ More options → Remove device → Yes, and pair them again.
If needed, update the Bluetooth adapter under Device Manager → Bluetooth → adapter name → Update driver. ^5^

If using Windows 10, provide the exact Windows version before applying a Bluetooth-specific settings path, because the available menus differ from Windows 11.
