Just add Audiomatic in vinyl mode and it goes away
It's all lo-fi trend now and we can buy plugins that add adds hum and noise

yes, these are you inputs on your soundcard using the pre-amps. if you put the gain of your pre-amps lower, the noise should be lower to. and changing inputs from instrument level to line levels makes it lower as well.

since you're not using the inputs this noise will not be routed to your outputs/

it's interesting to measure the noise of interfaces this way although I think the differences between interfaces are extremely small. my Focusrite is around -90 db with inputs on instrument level for my guitars. excellent.
