Windows 11 Microphone Not Working?
Windows 11 mic silent in Teams, Discord, and Chrome — privacy toggles, wrong default device, Realtek enhancements, exclusive mode locks, and driver reinstall.
Windows 11 microphone not working is the twin of no sound: wrong device, privacy lock, or a post‑update Realtek mess.
Quick map
| Symptom | Cause | Fix |
|---|---|---|
| All apps silent | Privacy off / muted array | Privacy + Sound settings |
| One app only | App device picker | Match OS default |
| After update | Default flipped to HDMI/headset | Re-select mic |
| Bluetooth headset | Hands-Free profile | Prefer stereo headset carefully; re-pair |
| Levels move, no voice | Enhancements / wrong channel | Disable enhancements |

1. Privacy (most common)
Settings → Privacy & security → Microphone
- Mic access On
- Let apps access On
- Let desktop apps access On
Corporate images may grey these out — that is policy, not Realtek.
2. Default input
Settings → System → Sound → Input
Pick the real microphone. Disable unused “Digital” or disconnected headset entries. Open Voice Recorder and watch the meter.
3. Enhancements and exclusive mode
Device properties → additional settings:
- Disable audio enhancements temporarily
- Uncheck exclusive mode allow apps
4. Drivers
Install OEM audio from Dell/HP/Lenovo/ASUS. Generic Microsoft packages after cumulative updates are frequent villains.
USB headset test isolates onboard arrays. If you later open a laptop for a mic cable, use an 11-piece precision screwdriver set on Amazon.
Bottom line
Enable mic privacy, fix the default input, then OEM drivers. App-specific silence is almost always the app’s own device menu.
Frequently Asked Questions
Mic works in Voice Recorder but not Teams?
Per-app permission or Teams using the wrong device. Allow mic for desktop apps and pick the same endpoint inside Teams.
Did a Windows update mute me?
Often. Updates reset default input to a disconnected headset or disable the array. Re-select the mic and reinstall OEM audio if needed.
Red mic icon in Discord?
Discord input device or sensitivity. Set input to your real mic and disable auto-sensitivity while testing.
Headset mic dead, laptop mic fine?
TRRS vs TRS jack mismatch, USB headset driver, or Bluetooth Hands-Free profile issues.
Hardware when?
No input device lists after OEM drivers, or physical damage after liquid — then board/array service.
