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. Trying to support a headset. Any advice is appreciated. Thank you very much.
