So Yesterday I go into my home studio and all of the clip lights and signal LEDs are on for all 8 inputs on my UMC1820. I was using it the night before and all was good. Now it wont pass audio or do anything at all. I've unplugged all of the ins and outs, disconnected power and usb, plugged it back in with nothing but the power cable and no change. As you can imagine I am a bit upset as I just purchased this at christmas and it didn't even last a month. I've opened a support case, but no response yet.... Has anyone experienced anything like this?
