I have some footage that I converted from red to prores444. I am able to view the converted mov in quicktime and the audio sounds fine. However, I when import it to Efter Effects, the audio previews and exports as white noise, I can see the waveform in the audiotrack, but it won't play. Any ideas what might be causing this?

My guess would be that AfterEffects is assuming something about the audio format which Quicktime is handling correctly but AE is not. Check your format settings; you might need to specify a different byte ordering (also called "byte swapping") or tell it to be explicitly 16-bit instead of, say, 24-bit. In Quicktime you can see what the audio format is via the movie inspector.

    +1 - The alignment is off. Expanding on what fluffy said, depending on the format the audio is in, check to see the format as far as PCM vs other raw formats; their sample size (16bit vs 24/32bit, etc) might be the same but the wait the samples are ordered might be off. Also check interleaving settings. – Qix - MONICA WAS MISTREATED Sep 1 '12 at 22:25
