Now I¡¯m even more baffled than before lol. The original receiver is passing audio to the rx pin just fine in both jumper positions.

Just glancing at the schematic:?? You can't be missing discriminator audio if you have speaker audio.?? Unless your J551A jumper is bad or something near there (circled).
