Are there any viable STM32 UAC2 (USB Audio Class 2.0) examples available?

Hi!

The Cube (STM32Cube FW F7 v1.15.0) examples seem to only show UAC1 examples, but I've seen references to working UAC2 applications on STM32.

I've seen some references to porting a driver from other platforms, or copying the descriptors from "Henry Audio USB DAC", but I was hoping it would be a bit more turn key in mid 2019.

Thanks!
