the only way to solve your problems is to take a logical step by step troubleshooting approach.
so, is your focusrite an 18i8 model ? i asked before, but you didnt reply.
this one ?
https://focusrite.com/en/usb-audio-interface/scarlett/scarlett-18i8
then i can look the tech details up.
IT SEEMS THERE ARE SEVERAL GENERATIONS 3 OF 18i8.
which is yours ? first ?

now the next is important. forget realband for a moment.
hook up headphones to the focusrite , and play any windows song or media file.
eg mp3 or wav. DO YOU HEAR THE SONG IN YOUR PHONES ?
AND DO YOU HEAR THE SONG IN YOUR SPEAKERS ?
AND DO YOU HAVE ANY FOCUSRITE APPLET in your taskbar ?
for setting of sample rates ?
ill check tomorrow for your reply.
