Problem with UR 12

Hello everybody! I have a problem with my new UR 12. When listening to music or voice recording , the sound disappears for few milliseconds. I have a PC with Windows 10. I tried UR12 to a PC with Windows 7 and a laptop with Windows 10 (home edition) and everything works perfectly. Please help me to solve the problem

You my friend have bought a dud and Steinberg cannot fix it. Apparently it is not them that is the problem but your computer. Although we don’t know exactly which computers/laptops it will work on. Lucky dip I guess. I would try and return it to where you bought it asap and not waste your time trying to troubleshoot because I guarantee your time will be wasted.
