Why Isn’t My Microphone Working in Zoom? 10 Reasons and How to Fix Them

🎤 Introduction: When Your Zoom Microphone Goes Silent

You join an important meeting, but no one can hear you. Or maybe your mic works, but the sound cuts out, crackles, or disappears.

This article covers 10 common reasons why your microphone isn’t working in Zoom and provides step-by-step fixes.

🔍 1. Microphone Not Selected in Zoom Settings

How to Check?

1. Open Zoom → Settings (⚙) → Audio.
2. Under “Microphone”, select the correct device (not “Same as System”).
3. Check the input level—if the bar doesn’t move, the mic isn’t detected.

💡 Tip: Click “Test Mic” to verify audio input.

🔌 2. Microphone Disconnected or Disabled

What to Do?

• Check connections (USB mics, headsets).
• Bluetooth headsets: Ensure they’re paired with your device.
• Built-in laptop mics: Some laptops disable them via function keys (e.g., Fn + F4 on HP).

Example: On MacBooks, mic access may be blocked in System Settings → Privacy & Security.
