I want to use the WM8994 on the STM32F769-DISCO for 24 bit acquisition on the Line In connector. Unfortunately the BSP code is fixed at 16 bit. :-(

[IWhit.2]

Has anyone done the changes necessary to switch up to 24/32 bit acquisition. It seems like its just AIF1_Control[6,5] on the WM8994 but the SAI is a complex beast and I'm not having a lot of luck. Any pointers would be greatly appreciated.
