I want to start streaming minecraft on my gaming laptop but how do i record game audio and our chat?

So I'm going to assume you're a child. You can't stream games if you don't have really good internet because you're not going to get a good bitrate that viewers like

What exactly do you mean by streaming? Do you mean recording them while you play, and then uploading them to Youtube for your friends to see? If that's the case, then you can use FRAPS.
