Steinberg UR-22 (First Edition) Ground Noise/Hum problem

Hey everyone,
I need your help!
I try to find a solution for my ground noise/hum problem with my Steinberg UR-22.
I’m hearing a static noise from my speakers Yamaha HS-7.
A Power Supply USB hub will help? or some specific cables? or DI-BOX?
Thanks for your help!
Have a nice day everyone! :slight_smile:
