Whenever a “user (in ODIN language it’s a peer) stops sending audio data (i.e. has deactivated the microphone) this event is triggered.
public void OnMediaRemoved(object sender, MediaRemovedEventArgs eventArgs);
You need to respond to this event and you need to remove the PlaybackComponent that you have attached to a game object before in the OnMediaAdded callback. You also need to remove the AudioSource from the Game Object which has been created by ODIN automatically.
