I can press 0 and hear my audio layer in the timeline. I want to be able to move my indicator along my timeline and hear my audio as I drag my indicator over a section. I am trying to match audio with text. I know After Effects can do it just as Premiere does where you move the pointer along the timeline and hear your audio. My audio is pre rendered and I am using a computer with 24GB of RAM. My version of AE is 5.5

No, it doesn't. You are mistaken. AE will only scrub audio by holding down Ctrl and it will do so in a much worse way.
