There is an Output but No Sound

Hi I recently purchased Cubase Elements 11, this is my first time using software like this. I have connected my Bass Guitar through my Focusrite Scarlett 4i4 interface and have been recieving both an input and output, the problem is that I have no sound whatsoever. I have tried reinstalling the app and changing my output to something different but i still have no results. When I restart my computer and open Cubase i can hear my instrument and audio files for a second before they are muted suddenly. Does anybody know the fix for this? If so please help!

Have you checked out outputs?

From top menu StudioAudio Connections. Click the Outputs tab at the top.

Look for a row that says Stereo Out. From there select your Focusrite Scarlet as the Device and set the Device Ports.
