I import a clip from my Canon HD camcorder and there's no sound at all. Anybody experienced this problem? The project sample rate and the clip sample rate agree (48000 Hz), the track is not muted, what could I be missing. I play the same clip with the Canon software and I hear the sound. I go back to Hitfilm and there's no sound. I import another soundifle to HitFilm and I can hear it. ?????
