No, *A*uthentication always takes place during the first unfold process. It actually can't be done anywhere else, save encryption between first unfold device and downstream rendering device (oh, that will be the 8x8+SE architecture then...).

So if there is no blue light, bit perfect MQA is not being received, or perhaps another setting is incorrect like outputting 1x digital?
