Duplicate audio usually means your app or client is playing two sources: the agent’s direct audio and the avatar participant’s audio.

Check your LiveKit output configuration and client playback path. If the avatar should be the only audible participant, adjust the app to play the avatar participant’s audio and mute or disable the direct agent audio path.
