Questions & Answers
1

I am using NGUI for menu creation. For sound on/off purpose, I am using toggle button which works correctly.

So what next I have to do ? Also this time I searched other posts for my current solution.
If you more information then I am ready to provide.

You can make your code independent of previous button state

Example :

Button Script :

public GameObject audioSource;
bool soundToggle = true;

OnGUI()
{
 soundToggle = !soundToggle;
 if(soundToggle)
 {
  audioSource.SetActive(true);
  //audioSource.mute = true;
  //audioSource.volume = 1.0f;
 }
 else
 {
  audioSource.SetActive(false);
  //audioSource.mute = false;
  //audioSource.volume = 0.0f;
 }
}

When the button is pushed toggle a boolean, set the AudioListener in your scene to inactive when the boolean is false.
