Yes adding sound to your project is not hard in After Effects. Alittle confusing sometimes as you do a preview you don't get the sound. To get the sound to play in After Effects you need to press the period key to preview the sound. You ask about tutorials. If you want many really good ones try these at Adobe.

Hope they help, if not in the sound but whatever else you may want to learn.
