Infinitely repeating sound when minimizing web player

Hello all. I have come across a rather strange occurrence that I have been able to find nothing on. When I run my game in a web player, if I minimize that web player and bring it back up, I get a sound that repeats throughout the rest of my scene. It is just a dun dun dun dun dun dun over and over and over again. It appears to be caused by the following script, but I have no idea why. Any suggestions?

using UnityEngine;

using System.Collections;

public class FinalMovieScript : MonoBehaviour {

public MovieTexture movieClip;
public GameObject movieTexture;
public AudioClip audioSound;
int movieCount = 0;

void Start()
{
	movieTexture.active = false;
}

void OnMouseDown()
{
	if(movieCount < 1)
	{
		movieTexture.active = true;
		movieTexture.renderer.material.mainTexture = movieClip;
		movieClip.Play();
		audio.Play();
		movieCount++;
	}
}

void Update()
{
	if(movieClip.isPlaying)
	{
		GameManager.popQuestion = false;
	}
	
	else
	{
		movieTexture.active = false;
		GameManager.popQuestion = true;
	}
}

}

Add an OnApplicationPause() {...} event handler where you silence audio by code. Make sure you turn it back on when you’re back to the game.

Cheers!
