Zoom Microphone Not Working? 10 Quick Fixes

Quick Fix

In Zoom, click the arrow next to the microphone icon and select the correct microphone from the list. Also check that you’re not muted – look for the red line through the mic icon. Most Zoom audio issues are simply wrong device selection or being muted.

Understanding Zoom Microphone Problems

When your Zoom microphone doesn’t work, others can’t hear you even though you can hear them. This creates frustrating one-way communication during meetings. The issue could be with Zoom settings, system permissions, or your microphone hardware.

FAQ

Why can others hear me sometimes but not always?

Intermittent audio often indicates a loose microphone connection, wireless headset battery issues, or background noise suppression cutting you off. Try speaking louder or disabling noise suppression in Zoom audio settings.

Why does my microphone work in other apps but not Zoom?

Zoom might not have microphone permission, or it’s selecting the wrong device. Check privacy settings and manually select your microphone in Zoom’s audio settings rather than using “Same as System.”

Can I use my phone as a microphone for Zoom?

Yes, join the meeting on your computer for video, then join audio via phone. In Zoom, click the arrow next to mic > “Leave Computer Audio” > “Join by Phone” and follow the dial-in instructions.

Why is my microphone very quiet in Zoom?

Go to Zoom Settings > Audio and increase the input volume slider. Uncheck “Automatically adjust microphone volume” if it’s making you too quiet. Also check Windows/Mac system volume for the microphone.

Does Zoom work with Bluetooth headsets?

Yes, but Bluetooth can be tricky. Ensure your headset is paired and connected before opening Zoom. Select the Bluetooth device specifically in Zoom’s audio settings, not “Same as System.”

Why does my mic work in test but not in meetings?

You might be joining with phone audio accidentally instead of computer audio. Click “Join Audio” in the meeting and select “Computer Audio.” Also check if the host has muted all participants.
