Microsoft Teams: Audio or Microphone Not Working

Can't be heard in a Teams meeting, or can't hear others? Here's how to fix audio issues in Microsoft Teams. Step 1: Check Teams audio device settings In a Teams call or meeting, click the three dots (...) > Device settings. Make sure the correct Speaker and Microphone are selected. If you're using a headset, select it here — not the built-in speakers. Step 2: Check Windows privacy settings Windows may be blocking Teams from using your microphone. 1. Open Windows Settings (Win + I) 2. Go to Privacy > Microphone 3. Make sure "Allow apps to access your microphone" is On 4. Scroll down and make sure Microsoft Teams is enabled Step 3: Test your microphone in Teams In Teams, click your profile picture > Settings > Devices. Click "Make a test call" — this will let you record and play back your voice to confirm the mic is working. Step 4: Check your headset/speaker connection Unplug your headset or speaker and plug it back in. For USB devices, try a different USB port. For Bluetooth headsets, disconnect and reconnect via Bluetooth settings. Step 5: Set the audio device as default in Windows Right-click the speaker icon in the taskbar > Sounds > Playback tab. Right-click your headset or speaker and select "Set as Default Device." Do the same in the Recording tab for your microphone. Step 6: Update audio drivers Outdated audio drivers can cause microphone issues. Open Device Manager (search for it in Start), expand "Sound, video and game controllers," right-click your audio device, and select "Update driver." Step 7: Restart Teams Close Teams completely (right-click the Teams icon in the system tray > Quit). Reopen it and test again.
