Common Teams Audio Problems

Audio issues can be frustrating. Here's how to fix the most common problems.

Others Can't Hear You

Check 1: Are You Muted?

Look at the microphone icon in Teams:

• If it has a line through it, you're muted
• Click it to unmute

Check 2: Correct Microphone Selected?

• Click the three dots (...) in the meeting
• Click Device settings
• Under Microphone, select the correct device
• Speak and watch the level indicator move

Check 3: Microphone Permissions

Your browser or app may be blocking the microphone:

Windows:

• Go to Settings > Privacy > Microphone
• Ensure apps can access your microphone
• Check Teams is allowed

Mac:

• Go to System Preferences > Security & Privacy > Privacy
• Click Microphone
• Ensure Teams is checked

Check 4: Physical Connections

• Is your headset plugged in properly?
• Is the mute switch on your headset off?
• Try unplugging and replugging

You Can't Hear Others

Check 1: Volume Up?

• Check your computer volume is not muted
• Check headphone volume
• Look for a volume control on your headset

Check 2: Correct Speaker Selected?

• Click Device settings
• Under Speaker, select the correct device

Check 3: Test Your Audio

Before meetings:

• Click your profile picture in Teams

Echo or Feedback

If others hear their own voice echoed back:

Solution 1: Use Headphones

Echoes often happen when using laptop speakers and microphone together. Headphones prevent this.

Solution 2: Turn Down Volume

Loud speakers can feed back into the microphone.

Solution 3: Only One Device

Make sure you've only joined the meeting from one device.

Choppy or Robotic Audio

Check Internet Connection

• Move closer to your WiFi router
• Close other programs using the internet
• Check if others in the office have the same issue

Reduce Bandwidth Usage

• Turn off your video temporarily
• Close browser tabs you don't need
• Ask others to turn off video if still having issues

Quick Fixes to Try

• Restart Teams - Close and reopen the app
• Leave and rejoin - Sometimes fixes glitches
• Restart computer - Clears many issues
• Try different device - Use phone audio as backup
