Hi Dave

Yes I agree the fast boot option in any windows build can play havoc with music applications and more .

As it gets up and goes before all things are really fully ready just a working set so to speak,

That is why disconnecting and reconnecting your device after the machine had properly loaded its drivers for the Scarlet worked.
This will be more noticeable if your device is not the default device for say audio as fast boot will load the default device first to get you going quick.
Just my thoughts.
Best regards
Mike
