I believe Teensy's TDM implementation would be called "TMD8". It has been validated with Cirrus CS42448.
I ordered 10 bare ICS-52000 chips from Digikey. Will make another attempt. Maybe the notwired.co boards are defective, with the mics acoustically damaged somehow? It did transmit data and was somewhat working, but only very slight sensitivity to sounds in the room.
Why do you give so little info every time you ask for us to help? This photo does not show how you actually connected to Teensy. We can't even see which wires are which pins in this photo! You also did not show the code you ran for this test.
Please understand this is not how we work on this forum. When you say you tried something and it did not work, you need to actually show us what you tried. A photo is good only if it gives meaningful info.
Your boss is not the only person unhappy. I am personally frustrated by your way of posting, starting too many threads, not showing how you actually connect the hardware.
Still I am trying to help you. But I am asking myself why I should spend even more time on ICS-52000?

I tried to connect the ICS52000 directly to the teensy 4.1, with some basic circuit recommended by the ICS52000 data sheet,

but it is still not working?

So , my boss is not happy.
