Not to address/counter your comment, but because it might be helpful: if that's a Focusrite interface, the company itself points to an open source project in its support documentation.

I haven't actually tested it, but it seems like it works for people, and it's solid enough to have the kernel component in the kernel. I found it while researching a possible move with my Vocaster One.

I have Scarlett 2i2G4. I may look into it. On the other hand, I have way more advanced stuff from ESI and Audient, which allows much more customization when compared to Scarlett, and they have no Linux support AFAIK.

Some hope for ESI, maybe: https://kb.esi-audio.com/?goto=KB00337EN

If it's one of those and class compliant, you might be able to access all of it through alsamixer or one of the many frontends (maybe too many, maybe one for you): https://en.wikipedia.org/wiki/Alsamixer

The Audient situation appears to be a proper nightmare realm with non-class compliant stuff, but there is a tool with a list of caveats longer than you might want to deal with: https://github.com/TheOnlyJoey/MixiD

It's more best case scenario as an escape hatch and less problem solved, but it's something.

		Well I'll test it when I have some time. ESI has a lot of routing flexibility on board, and I don't know how ALSA will present it to me, but I may report it here. I didn't expect Audient to work, actually.
