Answers.Body: <p>The MPEG4 has no audio settings. I chose h.264 and now I can see the Audio settings. So basically this MPEG4 has not audio output at all. That's why no audio is in the rendered video. This is very strange.</p>

Body: <p>I've been using after effects cs6 to make <a href="https://www.youtube.com/watch?v=7-AAl2SrHNo" rel="nofollow">intros</a> in my youtube template. They always render without sound. I've been exporting them as <code>avi</code> files. I'm currently making one in an mpeg4 format (assuming that is another name for mp4) since my other intros all have sound and they're mp4 files.</p>
  
  <p>I clicked "lossless" in the render queue and I changed the file format to avi. I checked "audio output" and didn't touch the settings inside that submenu and then I clicked OK and render. after waiting a while, AE spit out an intro file thats around a gigabyte in size and has no sound. What is the problem?</p>

Comments.Text: @RegisteredUser And where is your audio layer in the composition? As you can see, **in this composition is no audio**, if a layer consists of audio the audio Icon (right beside the visibility icon) will appear. Could you please add a more meaningful screenshot? What about the answers in the linked question?

  (Asked by: username_0 on 2015-08-13)
  
  I've been using after effects cs6 to make [intros](https://www.youtube.com/watch?v=7-AAl2SrHNo) in my youtube template. They always render without sound. I've been exporting them as `avi` files. I'm currently making one in an mpeg4 format (assuming that is another name for mp4) since my other intros all have sound and they're mp4 files.
  
  I clicked "lossless" in the render queue and I changed the file format to avi. I checked "audio output" and didn't touch the settings inside that submenu and then I clicked OK and render. after waiting a while, AE spit out an intro file thats around a gigabyte in size and has no sound.
