We have same audio problems as yours, Martin, but with decklink SP, using a anolog mixer too, captured level are too low, and output are too high (couldnt find a way to set input and output level +4db or +10db or somethings else in decklink preference like my old Pinnacle Targa 3000 board). So I have to lower the master level in Audio mixer in PPro in order to monitor and record to tape using decklink.
