Step 1: Check Privacy Settings
This is the #1 cause of mic issues on Windows 10. After updates, Windows often resets microphone permissions.
- Press Win + I → Privacy → Microphone
- Click "Change" and make sure microphone access is On
- Turn on "Allow apps to access your microphone"
- Scroll down to "Allow desktop apps to access your microphone" — turn it On
- Check that the app you're trying to use is listed and enabled
Step 2: Set the Correct Input Device
- Right-click the 🔊 speaker icon in the system tray → "Open Sound settings"
- Under "Input", select your microphone from the dropdown
- Click "Device properties" and make sure it's not disabled
- Speak into your mic — watch if the Test your microphone bar moves
Step 3: Check Sound Control Panel
The old-style Sound panel gives more control:
- Right-click the speaker icon → "Sounds"
- Go to the "Recording" tab
- Right-click in the empty area → check "Show Disabled Devices" and "Show Disconnected Devices"
- Find your mic → right-click → "Enable" if disabled
- Right-click your mic → "Set as Default Device"
- Double-click your mic → "Levels" tab → set volume to 80-100, make sure it's not muted

- If that fails: right-click → "Uninstall device" → restart PC
- Windows will auto-reinstall the driver on boot
Step 6: Restart Windows Audio Service
- Press Win + R, type services.msc, press Enter
- Find "Windows Audio" in the list
