'the negative terminal of the 22uF cap is tied to the positive terminal of the DC voltage source'

yes, that's the direction of the current flow ... the whole DC circuit 'flows' to the positive of the line level source, which actually carries the 'negative' audio signal right? the line level's negative flows to the negative terminal of the battery ... are you saying the battery should be reversed as well?

when you say it converts that bi-polar cap to a resistor I agree, but that circuit is also treating the battery as if it was a 'pre-charged' capacitor, and the whole thing is dumping DC into the line level source in reverse ... I was thinking that bi-polar cap should just be a high value resistor instead ... on the other hand it doesn't make much sense to reverse charge the line level output ... that seems like 'bad ju-ju' to me
