The 18i20 2nd Gen fortunately has got no zero-latency default routing
and unfortunately there is no way to change the routing using Linux or
iOS.

Not 18i8. The Linux mixer available for the Scarlett family does not
work for the 18i20 2nd Gen. Maybe you just need to add the 18i20's
identifier to the source code, but since I don't need it, I don't waste
my time with testing it.
