I have a .wav file in my composition that I see the waveform going across the entire composition. If I grab the first 10 seconds of my composition and hit 0 on the number pad, it correctly plays the audio the entire time. When I render that composition, making sure audio is enabled, it doesn't work. The resulting .mov file plays the audio for the first 5 seconds and then just abruptly stops.
I'm using the Creative Cloud version.
