One or more connected auxiliary content renderer device(s) are not ready in time. Playback is starting without them. Auxiliary content like closed captions or immersive sound might not play correctly.

Check the auxiliary content renderer devices and connectivity with the ICMP. Reload the content. Retry or restart the projector or the rendering device. If the problem persists, escalate the issue including a log package from the system and, if possible, from the rendering device.
