I located a headset (mic and headphones). Plugged them into the
headphone jack. It seems the mic was 'somewhat' active in that if I
clicked the mic it would register audio on the vumeter. I did a
recording and got some noise from it but it wasn't really clear. I don't
know if this means anything. I've attached the nothing.out and a
headset.out showing what has changed... Its considerably different than
the other simple ones. Thoughts?
