I found a work-around. After starting BIAB, instead of hitting the generate button, I open the Multi-picker window and not select anything. Then I hit the "generate" button and the song plays correctly with RealTracks. Why this works, I have no idea, but it is easy. Maybe my preferences are different from most people because I have BIAB open with the previous song loaded.
