Hello,

Normally you can use WM8994 as audio codec for STM32U5, 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.

WM8994 driver is available here.

Hello,

You can isnpire from STM32U575i evaluation board

It uses CS42L51 audio codec.

Edit: it seems CS42L51 is obsolete from Cirrus Logic website.

It suggests a part number replacement: WM8962B

Hope that helps
