Clear input and output signals on meters, full permissions on M1 Macbook Pro granted. Only possible anomaly I can see is I can't set separate input and output devices on the Prefs panel. When I choose Scarlet 4i4 for the input, it defaults to the same for the output, when the output should be the Mac's speaker (or "built-in"). If I change the output to "built-in", the input also changes to "built-in", which of course, defeats the whole purpose.
