I2S_CKIN Not Displaying in SAI UI

Hi there!

When I set up a fresh project for the STM32G431KB in STM32CubeIDE, let's say I want the SAI to be clocked by an external clock source.

So, in the prefs, I set Audio Clock Input (I2S_CKIN):

0693W000001cc9aQAA.jpg

Then I set up my Clock Configuration:

0693W000001ccA9QAI.jpg

Now one would expect now when I go to the SAI configuration, that my clock would be shown correspondingly, well, my friend, you would be wrong:

0693W000001cc3yQAA.jpg

Note how "Clock Source" is listed incorrectly as "SAI PLL Clock", not only that, but let's look at the code-gen to see what's REALLY happening:0693W000001ccBvQAI.jpg

Well look at that, it's actually set correctly, but confusingly displayed incorrectly in the GUI.

It'd be great to either get this fixed, or for someone to tell me whatever it is that I'm obviously doing wrong.

Thanks!

STM, surely this is an easy fix? Could someone please give me at least an answer that you've seen this bug and are taking a look at it?

The fact that this same setting DOES work for I2S and not for SAI seems to indicate that it should be able to be fixed in the UI.

Thanks.
