Surely missing something fundamental here, but I don't seem to be able to import audio of any flavor into AE. I've brought in copies of the same track as aif, mp3 and wav, and as well, a file from T&C Meyer tutorial DVD. In each case the file appears in the project panel, but when I pull it onto the timeline there is no speaker icon, no waveform, and of course, not sound. Actually the mp3 file does have a speaker icon, and a pull down to audio, but no waveform
My guess: you're still on the straight-out-of-the-box version of AE 10, and not the update to 10.0.2. It's easy to get: In AE, go Help>Update.
Disable any firewall or antivrus software temporarily before you do it, the reenable once you're done. Or just yank the internet connection out of your computer if you can and reenable at your leisure.
