Thank you for posting your question in the Microsoft Q&A forum.
Regarding your issue, it sounds like your microphone stopped working because a recent Windows update may have changed your input settings or audio drivers. This can cause the default mic to switch, permissions to reset, or audio enhancements to interfere with proper input.
Here are a few steps you can try:
- Reinstall Drivers
- Right-click the Start button and select Device Manager.
- Expand Audio inputs and outputs. Right-click your microphone/headset and select Uninstall device.
- Expand Sound, video and game controllers. Find your main audio driver (usually Realtek Audio or Intel Smart Sound).
- Right-click it and select Uninstall device.
- Note: Do not check the box that says "Delete the driver software for this device" yet.
- Restart your computer.
- Windows will automatically detect the hardware and reinstall a fresh copy of the driver.
- Check Optional Updates
Drivers are often tucked away in the "Advanced" menu now.
- Go to Windows Update > Advanced options > Optional updates.
- Look for any hardware-specific audio drivers there.
