My steinberg ur22c audio interface stopped working correctly today, at first the sound for playback began to be interrupted, and then disappeared altogether. I have been using this device for 8 months, and before that I did not encounter such a problem, all indicators work correctly, the power is stable, I also tried with an external one. I reinstalled drivers, windows system, tried on other devices, and everything does not work. At the same time, when recording a microphone, there is a signal, and everything is recorded, and when playing sound in a DAW or system, there is either nothing or little noise. I do not understand how to solve the problem, also in my country there is no support service for repair and exchange. Thanks for any help.
