something about play 24-bit i2s data.

Hello! I am using STM32F746N. I use i2s to connect a 24-bit microphone. Can the WM8994 play 24-bit sound? Does WM8994.c support 24-bit audio playback? If I want to play 24-bit audio, what files do I need to modify, thank you

The WM8994 CODEC is a 24-bit part and will support 24-bit input. The files to modify include the setup code for the CODEC as well as the setup for the I2S. These files are part of the sample code distributed by ST and then modified as needed by the BSP author.
