Hello, I have searched through the past posts on this topic, but I see no clear answer. What are the audio input capabilities? I don't see an audio-in jack. But perhaps there is some other way? Yes I am sure I can get a USB sound card but I am trying to avoid that. I don't need stereo or very low delay. I do need the ability to do audio out and audio in at the same time, with a moderate amount of signal processing.
