Just startin sounds like my issue exactly except I plugged my headphones into the headphones jack and still don't have any sound. I am trying to use two different mics, a AmicV- 2R dynamic and the other an AKG D8000M (also dynamic I believe). I can get guitar input in Ableton lite live 8 but nothing from either mic or mic input. I don't recognize the Sound windows shown above and haven't looked at anything like 4 line UX2 line 6. Not sure what that is.
very frustrating.
