Endless loud noise when using GuitarRig or ToneLib

I have recently bought UR24C. I connected it directly to my laptop using the original USB-cable. My guitar connected to UR24C. When I start GuitarRig or ToneLib, I get an endless loud noise as an output.

Here is the video demonstrating the problem

Drivers are official downloaded from the Steinberg website
Any ideas, what’s wrong here?

Have you tried using Input 1 (the one to the left) and activating Hi-Z?

Try running dspMixFx and disabling the Loop Back button, if it shows up as enabled (lit up).

@Romantique_Tp Thank you!!! LoopBack was the problem. This might look silly a bit, but I’m a newbie just started working with Audio interfaces :smiley:
