I don't see that option in my Adobe Media Encoder CC.

My answer is for rendering from AE. That pic looks like you've got Media Encoder set up ok. Can you use something like ffprobe or mediainfo to check whether there is an audio stream present? The lack of audio could mean: • there's no audio stream, • there is an audio stream which is silent, or • there's something preventing you from playing the audio properly in the encoded file.

I don't have enough reputation to select this as the answer yet but the `Audio Output On` was the trick. Pardon I didn't try it earlier. Thanks @stib

My video layer did indeed have a waveform and the audio icon was checked "on". It was when I followed your RAM Preview answer using the "0" key to activate the playback that on about the 7th or so try, the audio finally faded in on the playback as excepted. Rendering now in the Media Encoder. Will report back once the file is rendered. Thanks.

Turns out my render didn't have audio in the same style as my youtube link above. :(

@Mikeumus If ram preview is fine, check your render settings.

everything is setup to render the audio. I'm using the YouTube 720p present.

I have two keyframes (little white diamond shapes) that do a audio fade-in (-48dbs - 0 dbs). The last RAM Preview I did, the audio fade-in from those key frames seemed to be working.

@Mikeumus ok thanks for checking - sounds right :) you can also try to encode it directly in after effects. Go to the comp that looks ok and hit CTRL+M to add it to the render queue. You could render it as uncompressed and encode it later with media encoder to your youtube preference.

<p>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...</p>

Make sure that audio is on in your output module. In versions prior to CC you had two choices: on and off, recently they've added an automatic function that turns on audio rendering if the comp has audio.

In the render queue you'll see this if you twirl down the output module triangle:

![enter image description here](https://i.sstatic.net/8CFYs.png)

And you can set audio rendering in the output module window:

![output module](https://i.sstatic.net/sv3eu.png)

Note that the output module is what determines whether audio gets rendered. It can be on when you do a RAM preview, but if it aint on in the output module, you aint gettin' it.
