using System.Collections;
using UnityEngine;

public class PlaySoundBeforeQuit : MonoBehaviour
{
    [SerializeField] private AudioSource audioSource; // Drag & drop the audio source in inspector
    void Start()
    {
        Application.wantsToQuit -= WantsToQuit;
        Application.wantsToQuit += WantsToQuit;
    }
    private bool WantsToQuit()
    {
        Application.wantsToQuit -= WantsToQuit;
        StartCoroutine(QuitAfterDelay(1f));
        audioSource.Play();
        return false;
    }
    private IEnumerator QuitAfterDelay(float delay)
    {
        yield return new WaitForSeconds(5);
        Application.Quit();
    }
}

Note: The return value of the wantsToQuit event is ignored when exiting play mode in the editor. IMPORTANT: The return has no effect on iPhone. Application can not prevent termination under iPhone OS.
