I'm a bit stuck now, after years of happiness working with Windows and my 003 Rack. However, I just built a spiffy Windows 10 box, and plugged everything in. Curiously, I get no sound from the headphones, which used to work just fine. I have not re-routed anything in my studio. What should I look for? Right now I am listening to Inputs 1&2 through speakers, but can't listen through headphones through either of the headphone outs. I used to do this all the time. Something is odd.
