> I can't get audio by playing it normally.
You said that audio played when you used RAM preview. That is how you play audio.
Since you're new to After Effects, I very strongly recommend that you work your way through the materials here:
Oh I'm so sorry, I thought that since it said "Preview" that for some reason it basically meant I could play the audio on the After Effects program, but if I were to export the video to maybe a disc or try and upload it to a website, that the audio wouldn't work.I'm sorry, but thank you very much for clearing that up.
