I have the STM32446e board. I've been trying to get any sort of analog mic input working through the onboard WM8994 codec. None of the provided examples support this. Hardware background, so I'm confused by all the drivers. Any easy way to do this?

The examples only support the digital MEMS microphones on the board. I'm uncertain whether the BSP actually supports using analog in. The wm8994.c driver supports analog in, but I'm not certain this function is actually being called by the higher abstraction layers. Again hardware background, so it's difficult to understand all these BSPs, HALs, drivers, callbacks and whatnot. I just need to verify this functionality before rolling out a board with the STM/WM8994 combo. Any advice is appreciated. Thank you very much.
