Cubase 8 elements - cracking/fizzing sound

Hey,

Me and my band members have been working with cubase and while the instruments sound perfectly fine in the headphones the recording itself is just inaudible … Only cracking, fizzing, etc. In the distance you can hear the instruments, but utterly distorted.

How can we resolve that issue?

We use a Focusrite Scarlett interface and a Windows 10 64bit operating system.
