I often have a little noise on outputs, not always, but usually. Its not static, and it is not loud, but its annoying. What is more weird, there are cracks and pops in the output, if I turn wifi off or use the flight mode in Windows 10. I only can use Quantum 2626 with wifi on.

Do you know, what could help? Uninstalling software (such as Zoom, Voice Meeter, etc?), installing updates, or what?

This is my setup:
Intel NUC8 Core i7 Plato X8 passive Mini PC
Windows 10
Quantum 2626 via Apple Thundebolt3 cable

Thank you for your answer!

Thanks to the Presonus Support, the little noise was recognised to be "digital distortion" from the computers power supply. 
Using different power socket was the solution!

On the other hand, the cracks and pops are still there without wifi or in the flight mode. Any help?

So i7 cores have a function called c-states that you will probably have to disable. It means that cores will go to sleep when not in use and when they wake up (which can be milliseconds apart), it can create a pop or crackle. Presonus has an article about how to set up a power profile that will work well with interfaces:

Unfortunately I'm on mac and I'm still having this issue even after disabling c-states (I have a hackintosh). Hopefully this will fix it for you!
