Audiomovie and specify index mode

I can’t seem to get any audio out of a movie when I’m in specify index mode. I understand that there could be some conflicts with this since its not guaranteed that playback will be at the correct rate, but I’m just wondering if I should at least be getting some audio data, even if it’s messy, and if I were driving the frame at the right rate, it would be nice if the audio actually played correctly. I realize its probably more complex than meets the eye though.

Can you post an example? It works for me in the simple case
