Thanks Hugo. The Audiotron uses the 7312 chip rather than the 7212. I don't know how similar the two are, but I'm almost positive I have the CS8405 configured properly and it doesn't work right. I was unable to get a hold of any 7212 docs, but assuming they are basically the same, looking at the 7312 docs wasn't much help anyway. I couldn't find mention of the format the chip outputs through the DAI port, only the pinout on the signals.

I've had some people take a look at the signals heading to the DAC on the receiver and they seem to think that the channel frame size is 64 bits and that it is problematic for the CS8405, as it is at the extreme end of its capabilities.

Let's see what happens with a CS8420 when it comes in.
