STM32F7 Discovery board: use it as S/PDIF sound card (48 or 96 KHz), as USB sound card (48 KHz). Select the input interface via Touch Screen: have all the options and select any audio interface with one touch.
It provides also a nice VU Meter displayed on LCD ...
Very fancy and cost effective sound solution.

My project has also configured pins in order to connect an external I2S DAC, e.g. "Lyrebird", "True24" DAC, not limited to on-board DAC.
