How to put audio configuration on my laptop?

I deleted my audio configuration (what eva that is) off my laptop. now I have no sound and it is doing my head in... anyone no how 2 put it back on.

you are not giving a lot of information here. I'll start with some basics. Right click the the speaker icon in the bottom right corner of your screen and open up the 'master volume' window. Look for any mute boxes that are checked and unchek them, also make sure your tab controls arent all the way down. If that doesnt work open the control panel and open the 'sounds and audio devices' window and try to find the problem there. If that doesnt work use the windows help and support program in the start menu.

Assuming the questioner uses Windoze, the above answer should do. Otherwise...
