If it helps for a future purchase, Focusrite’s external interfaces have been amazing for Linux support.

To the point where I didn’t even notice; It just worked perfectly out of the box.

I’m assuming you’ve already checked this, but is your interface set to the same frequency/bit depth between Linux and windows? Or if it uses optical, whether it’s set to the same word clock source.

I considered this, but was forbidden: The limescale would leave it looking manky.

It might depend. If it’s not the only piece of evidence being used, then even an edited photo could be used as a data point to confirm another unedited one.
