I am not sure if this is common knowledge yet, but RME have released a remote app for the ADI-2 products.

This seems to work well for my desktop ADI-2 DAC FS, which is currently running via USB from a Windows 11 PC.
Some screenshots:
The above should give an idea of functionality. I have only just started trying it out, so I am not the expert here.
As a first impression, what I can say is that the app is a lot easier to use that messing about with sub-menus on the unit itself. Great stuff from RME!
