DACs for Odroid C2

Hi, gkkpch.
I have Odroid C2. Where i can see list what of usb dacs and i2s dacs support volumio 2 and volumio 3 for Odroid C2?

Thank you

USB Dacs: in principle most USB Class 2 versions, out-of-thebox.
USB Audio does not need a specific driver, linux has a generic one.
I2S Dacs: as a “hat” only the Odroid proprietary Hifi Shields.
I2S Dacs: wired, I only know of simple DACs which people have mentioned in this forum. Just use the search function in the Odroid thread.
There is not much more I can add, there is no list.
