Hi Wicked, I have had the exact same issue and came here looking for the fix. I saw a "Jam" error in the sticky, but I have repackaged and started over again from square one with the same result. I have tried two different methods in Wwise; selecting streaming and non. When going through and not selecting streaming; I get a gargle sound in the preview (no preview added). When I select streaming, I get silence like you did. Both ways I get the same problem; I can tune, the song starts, but no notes slide forward & it completes at 0% immediately afterwards. Went through EoF and inserted a 3 second silent, verified all the outputs from save (Wav & XMLs). I have tried both default and imported tones. Hope someone can help us.
