AE - Composition video file/layer missing audio In my case, I'm working with a file that does have audio, confirmed in the RAM preview and other checks mentioned above, however, I noticed after rendering, the first video file ha no audio (not even in the RAM preview any longer, the video layer is like my other imported video layers and still has the little audio icon with it). I had a audio fade-in on it but it worked before in the RAM preview and my audio fade-out on the last video still works fine. Some little option somewhere got toggled and yeah.... somewhere in there in those many great options AE provides...

The link to my .aep and project files on Google Drive:

Thanks for any help.  :)
Make sure the sound icon of the layer is enabled and check the audio waveform of the layer in your composition at this time.



For RAM Audio Preview see this answer: How can I preview with audio in After Effects and be able to pause / resume the preview?
