Your output from the Boss should work with the line in. Then set the record function in your sound system's mixer to use line in. Then if your Boss can be heard, Audacity can get it through its aux sounds recording, which just dumps anything going through the sound card/chip to its .au file.
I've torn so much hair out, forgetting to switch the source to line in on the soundcards over the years...
