I am trying to get my audio to be heard on my headphones for "karaoke" style recording been I'm warming up my voice and just having fun. But I can't seem to find a way to select the loopback for the output. Virtual is actually Virtual 1/2 and there's no Mixed 1/2, and then I finally heard it while going through each input option after choosing Main Out Left - Main Out Right. Is that how I'm supposed to do it? I'm using Edison to record and I don't have any speakers hooked up .
