I’m having exactly the same problem. I’m in a hurry (only got some days to finish the project) and have spent hours trying to find a proper solution, on the internet and just by trying some things myself, but nothing works. I thought it would be worth the effort, because who would think that there is no solution for an incompatibility between a highly popular microphone, the H4N, and a computer program made by a giant as Adobe? Very frustrating and time-waisting. I guess I’ll have to try some amateur technique, like recording it separately and than dragging it into Premiere Pro. Of course I still hope I’ll find a decent answer.
