Can’t hear the other person? They can’t hear you? No audio at all?
This is a very common issue and in most cases it’s caused by your computer or browser using the wrong microphone or speaker.
This guide shows the exact settings to check so you can fix it quickly.
Most common causes
Wrong microphone selected
Wrong speakers selected
Browser mic permission blocked or using different microphone
External mic connected but not set as default
These steps resolve the issue in the vast majority of cases.
Step 1: Check your computer’s default audio settings
Windows
Open Settings → click System → click Sound
Look for Input and Output
Input = what you speak into (your microphone)
Output = what you hear sound from (your speakers or headphones)Usually, these should match (ie: If you’re using a headset, both should be set to that headset).
Make sure:
Input is set to the microphone you are actually using
Output is set to the speakers/headphones you are actually using
If you don’t have any external microphones connected, the built-in internal microphone will be the only option.
Once set, close Settings.
Mac
Click the Apple menu (top‑left)
Select System Preferences
Click "Sound"
Look for the Input and Output tabs
Input = what you speak into (your microphone)
Output = what you hear sound from (your speakers or headphones)Usually, these should match (ie: If you’re using a headset, both should be set to that headset).
Make sure:
Input is set to the microphone you are actually using
Output is set to the speakers/headphones you are actually using
If you don’t have any external microphones connected, the built-in internal microphone will be the only option.
Test the input volume of the microphone you've selected and adjust if needed using the volume slider while speaking.
Once set, close Settings.
2. Check your browser settings
Even if your computer settings are correct, your browser can block or override your mic.
In your browser:
Click the site controls icon (the sliders icon) next to the URL in your browser’s address bar
Make sure Microphone is set to Allow
Click the > next to Microphone to see which microphone is being used
Select the correct microphone if needed
Refresh the page and rejoin the call
If microphone access is blocked, audio will not work.
Step 3: Quick test
Run a quick Network and Audio test to confirm everything is working.
