Vital Check
Before diving into software fixes, confirm these basics:
- Physical Mute: Check the physical toggle on your headset or laptop.
- Default Device: Ensure the correct mic is set as 'Default' in Sound Settings.
- Privacy Toggle: 'Microphone access' must be ON in Windows Privacy settings.
- USB Port: Try a different port if using an external USB microphone.
Why Is Your Mic Silent?
The 2026 Windows 11 architecture implements strict App-Level Sandboxing. Often, after a security update, Windows revokes microphone permissions for third-party apps like Zoom or Teams to protect user privacy. Additionally, the transition to Universal Audio Architecture (UAA) can cause older drivers to become unstable, leading to the "Microphone not detected" error.
