The Galaxy S7/S7 Edge does not support USB audio. For anyone interested in the S7, keep in mind you won't be able to use a portable dac w/ it. This is w/ the stock Touchwiz rom. Maybe it'll work with root.
I have the Exynos S7E and it works with my Dragonfly Black, Fiio Q1, iBasso D14, Topping NX2 and Asus Xonar U3 all with stock rom. Root is needed with the DFB to fix the volume issues but it works without root with the other DAC/Amps. With UAPP the DFB works properly and no need for root.
When you connect a USB DAC it routes audio by default unless disabled in developer options, in the pull down menu it even allows you to switch between audio outputs. I'm sure that there will be some DACs that don't work but it is not universal that DACs don't work with the S7E (Exynos). I can't comment on the Snapdragon versions.
