Audio is unavailable when joining

Identify what is missing

Check whether you cannot hear session audio, your voice cannot be heard, or both. Use a desktop or laptop and connect the microphone and speakers or headphones you intend to use.

Check audio settings

If you cannot hear sound

1. Check that your speakers or headphones are connected and the volume is turned up.
2. Check your computer's selected sound output, especially if you recently connected a headset.
3. Check whether the Train Lens browser tab or site is muted.

If your microphone is unavailable

1. Check that your microphone is connected and any physical mute switch is off.
2. Check the microphone selected in your computer's sound settings.
3. Review microphone access for Train Lens in your browser and for the browser in your computer's privacy settings.

Test again

Follow any instructions shown after a settings change. When you can join, check with the trainer or another participant that you can hear each other.

If settings are locked, ask your IT team for help. For more context, read Browser permissions required by Train Lens in Account and access.

If audio is still unavailable, use Information to include when reporting a problem and say which direction of audio fails.
