I a currently editing a video and imported a .avi movie into my After Effects project. I went to check the RAM preview, but there was no sound. I checked the audio preview and there still was no audio. I checked the waveform and it showed a straight lines, showing that there was no audio being produced from the video. I checked the video to see if there was sound playing and I determined there was. I also have another .avi file in the project and it plays audio with no problem. Please help! Thanks in advance!
