AddNotifyAudioDevicesChanged 

    Namespace: SynicSugar.RTC

    public void AddNotifyAudioDevicesChanged(Action OnDeviceChangedAction = null)
    public void AddNotifyAudioDevicesChanged(string currentSceneName, Action OnDeviceChangedAction = null)
    public void AddNotifyAudioDevicesChanged(GameObject MoniterTargetObject, Action OnDeviceChangedAction = null)

    Description 

    Register to receive notifications when an audio device is added or removed to the system.
    Action is triggered when the device is added or removed.
    The way to cancel this notifier is in MANUAL by calling RemoteNotifyAudioDevicesChanged(), or in AUTO when the current scene changes or when the object becomes inactive.

    This notify is mainly used when the user switches the device configuration on the setting screen (to display new devices on dropdown).
    In normal, Library automatically switches removed device to the available one. We don't need to moniter devices in game. EOS Document
