Definitely, use ASIO not ASIO4ALL. That alone may do it. ASIO4All is not ASIO; it is a wrapper for WDM.

I have several first-generation Focusrite Scarlett units, 6i6, 18i8 and 18i20. I just added a new second generation 18i20 to replace the older one, so I'm seeing the new Mix Control software for the first time. It's a bit puzzling.

I see you selected Custom in your screen capture. Once I figure out this new mixer, I'll come back to this thread.
