I'm using the Action Products XLR Audio Adapter “Calliope” with my Epic in beta build 2.05. After rebooting I sometimes loose my audio. The green buttons (lights) turn Red. I pulled out the mini plugs and tried spare XLR to mini plug sound cables. No joy. Re-set up the audio Audio/Video>Audio Input>Unbalanced. There's another menu where you can choose the input, Brain or Pro-module. When I turn it to pro module I get green lights. Anybody having similar issues?
