Ignore! All is well! I really couldn't see where the negative pad went off to, hence the question about "Can I put it anywhere" BUT when I looked really closely, it seemed to go to a thru hold right by the corner of the audio jack. (Top thru hole in a line of 3) So I popped a dab of solder to the other side and voila! I have audio, and video, and the stench of fish in my nose! Huzzah!
