Re: Can't hear sound track in the time line to sync w/the puppet tool by Tristan Nieto on Oct 2, 2009 at 3:06:00 pm
Unless you're RAM previewing your composition, After effects won't output any sound.
In general, doing anything in AE to sync with sound isn't that easy. My usual plan of attack is to get very familiar with the audio file and the sound waveform. Remember the lines and what they look like on the waveform, then animate to that.
