On Windows, the most relevant checks are microphone privacy permissions, desktop app access, input selection/level, and audio driver detection.
- Verify Windows microphone privacy settings.
- Windows 11: Start > Settings > Privacy & security > Microphone.
- Confirm these are turned on:
- Microphone access
- Let apps access your microphone
- Let desktop apps access your microphone
- Desktop apps do not appear as individually switchable apps. Their access is controlled by Let desktop apps access your microphone.
- If using Windows 10, check the equivalent path.
- Start > Settings > Privacy > Microphone
- Confirm:
- Microphone access for this device
- Allow apps to access your microphone
- Allow desktop apps to access your microphone
- Check whether the microphone is selected and receiving input.
- Windows 11: Start > Settings > System > Sound.
- Under Input, select the microphone.
- Use Start test, speak normally, then Stop test and Play to confirm capture.
- If needed, increase the Input volume slider.
- If the input meter does not move in desktop apps but works in system tools, this still points back to app permission scope or app-specific access.
- If the microphone is not detected by Windows in affected scenarios, reinstall the audio driver.
- Warning: uninstalling drivers can temporarily remove audio devices until restart/reinstall completes.
- Open Device Manager.
- Expand Sound, video and game controllers.
- Right-click the audio device and select Uninstall device.
- On Windows 11, select Attempt to remove the driver for this device if shown.
- Restart the device.
- If Windows does not reinstall automatically, in Device Manager select Scan for hardware changes.
- Then right-click the audio driver and select Update driver.
- If using Teams desktop, verify OS privacy access first.
- In Windows, Teams requires microphone access through the Windows privacy settings.
- For the Teams desktop app, ensure Microsoft Teams (work or school) is enabled where listed, and restart apps or the device after changing toggles.
- If the toggles were already on, turning them off and back on can help apply the setting.
- If using Teams on the web in Edge, verify browser permission.
- In Edge, go to Settings and more > Settings > Cookies and site permissions > Microphone.
- Turn on Ask before accessing (recommended).
- When prompted by the site, select Allow.
- A blocked site permission in Edge can prevent microphone use even when Windows microphone access is enabled.
- If the issue is low or inconsistent pickup rather than total failure, verify microphone level.
- Windows 10: Start > Settings > System > Sound.
- Under Input, select the microphone, open Device Properties, then adjust Microphone and Microphone Boost on the Levels tab.
- Windows 11: Start > Settings > System > Sound, select the microphone, and adjust Input volume.
Because the microphone already works in Voice Recorder and system tests, the strongest supported check is whether Let desktop apps access your microphone is disabled or restricted. On managed company devices, that setting is the direct Windows control for desktop app microphone access.
