What is SPI mode CPOL CPHA for ADAU1701?
There seems to be quite a bit of confusion over ADAU1701 and SPI mode. What is it?! This post seems to indicate it's SPI mode 0 (CPOL=0 CPHA=0), RE: ADAU1701 SPI mode This says (not specifically about

The difference between AVC and AGC
Hi, The block "AVC" is used. The curve of this AVC is as follows: it follows the input with a gain of -18dB and saturates at level of 0.538Vcc (crete-to-crete). The 0dBFS level is 1.1Vcc, so here 0.53
