I don't want to seem to harsh.
Your question is premature and poorly asked. You should (1) use the search feature to find and read the previous posts where people already asked questions like yours, about sound. If that doesn't give you the info you need, then (2) post your question, but give a little more information. We need more info in order to give you a useful answer. "i believe i have install everything need to work" really gives us nothing to go on. Maybe if you told us what you've installed, we might be able to find what you missed. We are all here to help each other, but don't expect us to care more than you do, about your problems. If you aren't interested in expending any effort, we won't be either.
I don't want to piss you off or chase you away, just you remind you of some basic netiquette.
