If the microphone settings already look correct, use this Windows 11 troubleshooting path:
- Check microphone privacy access again in the Windows 11 location:
- Start > Settings > Privacy & security > Microphone
- Turn on Microphone access
- Turn on Let apps access your microphone
- Turn on access for the affected app if it appears in the app list
- Make sure Let desktop apps access your microphone is also On for apps such as Zoom
- Confirm the correct input device is selected:
- Go to Start > Settings > System > Sound
- Under Input, go to Choose a device for speaking or recording and select the laptop microphone or headset microphone actually in use
- Select the > next to the device and run Start test under Microphone test
- If the test does not detect voice input, continue with the next steps
- Check simple hardware states:
- If using a headset, make sure its Mute button is not on
- If using Bluetooth audio, make sure the device is still paired and connected
- Make sure the microphone or headset is connected correctly
- Increase and test microphone input volume:
- In Start > Settings > System > Sound
- Select the microphone under Input
- Under Input settings, use Start test and adjust the Input volume slider if needed
- Run the built-in sound troubleshooter:
- Go to Settings > System > Sound
- Scroll to Advanced
- Choose Output devices or Input devices under Troubleshoot common sound problems
- Select All sound devices under Advanced for more options
- Reinstall the audio driver if Windows is not detecting the microphone properly:
- Right-click Start > Device Manager
- Expand Sound, video and game controllers
- Right-click the audio device and select Uninstall device
- If shown, select Attempt to remove the driver for this device or Delete the driver software for this device, then uninstall
- Restart the laptop
- If Windows does not reinstall it automatically, return to Device Manager, right-click Sound, video and game controllers, and select Scan for hardware changes
- Then right-click the audio driver and select Update driver
- Check Windows Update optional driver updates:
- Go to Settings > Windows Update > Advanced options > Optional updates
- Install available driver updates, then restart
If the microphone still worked previously in Zoom and then stopped while all settings appear correct, the most likely causes in this scenario are the selected input device changing, microphone privacy access being reset, or the audio driver needing reinstall/update.
If the built-in microphone still fails after driver reinstall and updates, the next step is to have the laptop checked for a possible hardware issue with the internal microphone.
