Hello Unity Answers,
I’m having a problem with the sound when the question is displayed on screen.
When I collide into the first box the question appears on screen and the countdown sound begins to play and if i press a button it will stop. Which is great as this works how I want. 
However If I approach the second question box, the countdown sound doesn’t play upon collision but will only play when I select an answer? I have exactly the same code for Question 1, in the Question 2 class so not sure what is wrong.
All advice & suggestions welcome.
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class Trigger : MonoBehaviour
{
public GameObject guiObject;
private Question1 guiScript;
public AudioSource cubeAudio;
public AudioSource countdownAudio;
void Awake ()
{
guiScript = guiObject.GetComponent<Question1> ();
guiScript.enabled = false; //Turn off the script, so the OnGUI function doesn't draw the question window
}
void OnTriggerEnter (Collider other)
{
if (cubeAudio != null) cubeAudio.Play();
if (countdownAudio != null) countdownAudio.Play();
guiScript.enabled = true;
Destroy (this.gameObject);
}
}
Question 1 code
