I have modified the ADC_DAC_Playback Example project to get TDM4 and also TDM8 working.
Then I added the USB Audio DEMO for ADSP-SC573 and modified the configuration settings for ADAU1962A (TDM8) and the audio is distorted.
The best way to describe this is that is sounds tinny (metalic) but all the audio channels are correct.
I have examined DBCLK, DLRCLK, DSDATA1 on the scope and this is how I confirmed that TDM8 looks to be working correctly here.
I am happy to share project if required.
Note I have sent previous requests to support & I have open support tickets but I've not had any response for a while so I'm hoping this proves more fruitful.
Thanks in advance,
