Thank you, Prock👍 I tried that but when I open the Steinberg USB Control Panel there is only an about and ok button and they do nothing. There are no I/O settings at all. Thanks for the idea and for bumping my thread, I really want to get my new monitors working. I’ve tried playing with the settings in Sound, Midi/Audio, and Logic, none of which results in the monitors working. I’ve hooked my phone up to them and they do work…
