I'm quite new to After Effects, anyway I have an After Effects project with a composition that has an audio layer.
The audio is a .m4a file (recorded from Samsung Galaxy S4).
The composition is about 5 minutes long in total, however when I try to do a RAM Preview it only buffers about a minute or two max that I can play back to test if it works OK. The audio plays back in the RAM preview.
When I add the composition to the render queue, I set it to render as H.264, which has Output Audio ticked (I've checked by clicking on the options pop-up and even unticked and ticked again for Audio). Audio is set to 48.000 kHz, 16 bit, Stereo. No other settings were changed.
The final output file is .mp4 and does not contain any sound. I'm playing back with VLC player but it's always silent...
