Questions answered in these manuals
What is the issue with the S/PDIF transmitter validity bit?
The validity bit is internally hardcoded to logic high, which indicates invalid data according to the S/PDIF specification, potentially causing receiving ICs to ignore the audio data.
From: Analog Devices ADAU1442/ADAU1445/ADAU1446 Silicon Anomaly Sheet
How can the S/PDIF validity bit issue be worked around?
Audio data should be routed to the serial ports and then to an I2S-to-S/PDIF transceiver IC instead of connecting directly to the SPDIFO pin.
