Hello,

You can isnpire from STM32U575i evaluation board

mALLEm_0-1766661545359.png

It uses CS42L51 audio codec.

 

Edit: it seems CS42L51 is obsolete from Cirrus Logic website. 

It suggests a part number replacement:  WM8962B

Hello,

Normally yes, it was already used in some ST Eval boards like STM32F769-EVAL using SAI interface:

(From STM32F769-EVAL schematics/MB1219). STL32U585AII6Q has tow SAI instances SAI1 and SAI2.
