Hardware Mute Switch Check
Inspect your headset cable or earphone inline control for a physical mute toggle or volume wheel turned down.

When a microphone fails, the issue almost always stems from one of four checkpoints in the audio pipeline:
1. Physical Hardware & Connection: Unplugged cables, broken TRRS jacks, or physical mute toggles.
2. Operating System Permissions: Windows 11 Privacy toggles or macOS System Settings blocking app access.
3. Device Selection: The system default is routed to an inactive virtual cable or disconnected Bluetooth device.
4. Browser Site Permissions: Chrome, Safari, or Firefox blocking site access to mediaDevices.

Frequently Asked Questions
Q.How do I know if my microphone is physically broken?
Plug the microphone into a different computer or a smartphone. If it fails to register on multiple independent devices, the internal capsule or cable is damaged.
Q.Why does Windows say "No input devices found"?
This usually indicates a missing audio driver. Open Windows Device Manager, expand "Audio inputs and outputs", right-click your microphone, and select "Update driver".
