I'm trying to connect Studio One Artist to my mixer using USB. It outputs to the mixer fine but despite many hours/days I can't get an input from the mixer. I have ASIO4ALL installed and when I open the audio device control panel the USB input has an X next to it and says unavailable. There also seems to be a problem with the sound setting in Windows 10, it's showing a USB input and output when the mixer is plugged in but is not showing and sound in the sound control panel. I've had this working in the past so I know it's possible, I think it was when I had Studio One Trial version. Any online instructions or youtube help doesn't work.
