hey guys, heres the code iv done so far for the audio stuffs:

Sound Management:

//****************************************************************************************************

public var levelNo: int = 1;

    cam = GameObject.Find("PC Camera(Clone)");
}
//****************************************************************************************************

function Update()
{   
    pcZ = pc.transform.position.z;
    camZ = cam.transform.position.z;

    if(pcZ > (camZ - 10) && firstPlay == true)
    {
        cleanUp();
        clipNo = (levelNo*2) - 2;
        firstPlay = false;
        Instantiate(sounds[clipNo], cam.transform.position, transform.rotation);
    }
    else if(pcZ <= (camZ - 10) && firstPlay == false)
    {
        cleanUp();
        firstPlay = true;
        clipNo = (levelNo*2) - 1;
        Instantiate(sounds[clipNo], cam.transform.position, transform.rotation);
    }
}
//****************************************************************************************************

function PlayPCSound(soundName: String)
{
    switch(soundName)
    {
        case "jump":
       
            break;
           
        default:
            levelManager.DisplayMessage("Sound Manager: ERROR! invalid sound clip name.");
            break;
    }
}
//****************************************************************************************************

function cleanUp()
{

    Destroy(soundObj);

    soundObj = GameObject.Find("Sound4(Clone)");
    Destroy(soundObj);
    soundObj = GameObject.Find("Sound5(Clone)");
    Destroy(soundObj);
}

Play Sound:

var clip: AudioClip;
var Cam: GameObject;

function Start()
{
    AudioSource.PlayClipAtPoint(clip, Cam.transform.position, 0.5);
   
}
var clip: AudioClip;
var Cam: GameObject;

function Start()
{
    AudioSource.PlayClipAtPoint(clip, Cam.transform.position, 0.3);
   
}

function End()
{
    Destroy(this);
}
