Thanks Stan,
?
All 4 pins have nice clean 12.7KHz sine waves at 630mV p-p so is there anything I can check on output of PCM1804 to ensure that is the problem and not other supporting components.
?
If it really looks like PCM1804, I will pull this one again and replace with a new one.
?
I appreciate the info and it is cool to see it for myself.
