There is no 'AudioSource' attached Error

Questions & Answers
1

I am getting this error but I have audio attached to it. I have deleted the component and even rebooted. Weird issue.

So here is the error:
MissingComponentException: There is no ‘AudioSource’ attached to the “Input-Escape-MainMenu” game object, but a script is trying to access it.
You probably need to add a AudioSource to the game object “Input-Escape-MainMenu”. Or your script needs to check if the component is attached before using it.
InputEscape+c__Iterator6.MoveNext () (at Assets/Extras Created/InputEscape.cs:47)
UnityEngine.MonoBehaviour:StartCoroutine(IEnumerator)
InputEscape:Update() (at Assets/Extras Created/InputEscape.cs:40)

here is the code. It only gives the error after pressing the spacebar

using UnityEngine;
using System.Collections;
///////////////////////////////////////////////////////////////
public class InputEscape : MonoBehaviour
{
    ///////////////////////////////////////////////////////////////
    public GameObject mainMenuBtn;          //	quit button
    public GameObject nextBtn;			    //	next button
    public GameObject overHeadBtn;          //	overhead button

    public GameObject effectNewBestScore;

    new AudioSource audio;
    public AudioClip menuSound51;
    ///////////////////////////////////////////////////////////////
    void Awake()
    {
        audio = GetComponent<AudioSource>();

        mainMenuBtn = GameObject.FindWithTag("MainMenuButton");        
        overHeadBtn = GameObject.FindWithTag("OverHeadButton");
        effectNewBestScore = GameObject.FindWithTag("BestScore");

        nextBtn = GameObject.FindWithTag("NextHoleButton");
    }
    ///////////////////////////////////////////////////////////////
    void Update ()
    {
        if (Input.GetKeyDown(KeyCode.Escape))
        {
            CanvasButtonsOnOff.fire1ButtonPressed = true;

            mainMenuBtn.SetActive(false);
            nextBtn.SetActive(false);
            overHeadBtn.SetActive(false);

            //destroy settings-1, settings-2.....courses
                Destroy(GameObject.FindWithTag("settings-all"));

            StartCoroutine(WaitForMainMenu2());
        }
    }
    ////////////////////////////////////////////
    IEnumerator WaitForMainMenu2()
    {
        audio.PlayOneShot(menuSound51, 1f);
        while (audio.isPlaying == true)
        {
            yield return null;
        }

        effectNewBestScore.SetActive(false);
        Application.LoadLevel("MainMenu");
    }
    ////////////////////////////////////////////
}

Should it be

private AudioSource audio;

?

Hi
try making a public or private audioSource variable instead of new audioScource

( private AudioSource audio ; )

Start(){
audio = getComponent(AudioSource) as AudioSource;

}

I was have this error too.
In my case maybe it happened because I add some audio files to project folder through file system.
I heard it may cause some bugs.
But, then I re import all audios it solved the problem
