Is there any way that I can test whether audio is being sent correctly? I have my default playback device as my interface, but the only audio that I can hear is from my iOS device. I can't hear things like audio from my browser or a song on continuous playback no matter how much I fiddle with the patch bay. I'm fairly certain that I know how the patch bay works since I'm watching a TV show on my iPad right now, but is there anything that I could be missing?
As an aside, what is the purpose of the analog mixer? I haven't been able to make heads-or-tails of anything I've been reading about it.
