I’ve had the UR22C for years and have never been able to get it to work. I gave it another try today and finally got Audacity to recognise it as a recording and playback device - this is probably user error.
When I try to record through a microphone into Audacity the levels do not move much, even when I have the gain and output levels at max.
These are Audacity questions - you should probably pose them in an Audacity forum.
For peace of mind and to rule out issues with the UR22C, you could download a Cubase trial version and give it a test run. That’s where the forum comes in.
Now that I think about it, I have never heard of a broken Steinberg audiointerface - it doesn’t mean there are none, of course.
