Sound works but Mic does not work

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

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

Windows 10

1. Open Settings → System → Sound.
2. Under Input, select the microphone in Choose your input device.
3. Speak and watch Test your microphone.
4. 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

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

4. Select the recovered microphone in Teams

After Windows successfully records sound:

1. Open Teams.
2. Select Settings and more (…) → Settings → Devices.
3. 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.
4. 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:

1. Right-click Start → Device Manager.
2. Expand Sound, video and game controllers.
3. Right-click the audio device and select Uninstall device.
4. 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.
5. Restart the laptop. Windows should reinstall the audio device automatically.
6. If it does not, open Device Manager and select Action → Scan for hardware changes.
7. 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.
