Hi everyone
I want to use ANC feature using ADAU167
I have bought PDM mic for input.
So at first I was testing with single mic and pair of headphones
Here is my setup
PDM mic connections
CLK -> BCLK_IN3

Mic is working, I have tested with simple digital mic custom program
Now I am working on NR example

Hello:
I will try to help (I do not currently have a 1467 board hooked up, so please understand I will do my best).
I would recommend connecting signal level detectors to ensure that you get a visual indication that signal is getting into your project.
Also, verify the connection number of the input and output connection paths.
Regards,
