How to troubleshoot speaker or microphone issues

Check the device

  • Make sure the cable connection with the microphone is fully inserted into the appropriate port.
  • If Zoom fails to detect your microphone, unplug the device and plug it back in.
  • If it’s a bluetooth device, ensure that it is turned on and connected properly.
  • Make sure that you are using a supported USB device for Zoom.
    Note: USB devices not listed within the above article may still work with Zoom. However, the devices listed are what we recommend for the most optimal experience. Supported USB devices less likely encounter audio issues.
  • Ensure the microphone is not on mute.
    • If you see the muted Audio icon in the meeting controls, click it to unmute yourself:
      If you are still muted, the host may have muted you upon entering the meeting. Ask to be unmuted by sending a chat message to the host.
    • Some microphones or headphones have a physical mute button, switch it off to unmute yourself.
  • Increase the volume on your computer or laptop using the volume buttons or notification panel. Even if the speaker is turned on in Zoom, your device's volume might be set to mute or vibrate only.
