Silent .3 seconds at beginning of playback on Mac, but not PC

A .wav file I exported from Audition on a Mac is acting strangely on playback in AfterEffects. The sound doesn't actually play until about .3 seconds into the clip. This occurs on Mac only. On a PC the file plays fine. When viewed in Audition on both platforms the file waveform is identical. The file plays fine in AfterEffects on a PC. But in AfterEffects on my Mac, the beginning is truncated. On my Mac, the file plays correctly in Quicktime Player, VLC, and Apple Music. It only misbehaves in AfterEffects.
