Go to Composition > Preview and make sure that Audio is checked. If it is, then just choose Composition > Preview > RAM Preview and you will hear your audio during the preview. Sometimes, though, the first time through the preview the audio will be slightly shifted, like a couple frames early or late, IIRC, so you should just let the preview go on for at least a couple times to check the actual sync.
