UR12 - No sound from speakers\headphones

Hello! I have some issues with my device. So i can’t hear something from speakers\headphones. I followed instructoins and installed device and drivers correctly but still have no any sound. I disabled integrated motherboard audio-device in BIOS but it still doesn’t work for me. So my speakers connected to a computer (into motherboard), maybe it should be connected to UR12, isn’t it? Thank you.
