During the pandemic I tested a lot of USB sound cards on Linux -
actually the Focusrite Scarlett Solo was one of the best in terms of
latency (and also in terms of interrupt timing jitter - this is crucial
when it comes to very low latency and high CPU load):

That is really interesting.
Two questions come to mind:
1) How did you measure that?
2) How do I interpret it? Naively it seems Focusrite Scarlett Solo is best at 2ms. What
are the other two columns?
With the HiFiBerry GPIO caps I get an even better
performance, both in
terms of latency and jitter.
I have been tempted by the HiFiBerry, I am put off as it seems "line in" is not
front of mind for them. It is for me. How have you found it? Is the sound quality OK?
Best,
Giso
