 void OnGUI(){
 if(yMute){
             if (GUI.Button(new Rect(100, 10, 100, 50), "",Y))
             {
                 AudioListener.volume = 0.0F;
                 muted = true;
                 nMute = true;
                 yMute = false;
             }
         }
         if(nMute){
             if (GUI.Button(new Rect(100, 10, 100, 50), "",N))
             {
                 AudioListener.volume = 1.0F;
                 muted = false;
                 nMute = false;
                 yMute = true;
             }
         }
     
     }
 
     void Start () {
         yMute = true;
 
     }
     
     // Update is called once per frame
     void Update () {
         if (yMute == true) {
             nMute = false;
         }
         else {
             nMute = true;
         }
     }

The problem is that your using multipe variables to detect if user have alredy muted or not the sound. And you reset to false yMute variable at Start, so when you back to the scene, yMute is set to true, but nMute keep his old value.

Use only one variable would be better, something like:

 void OnGUI()
 {
     if(!isMuted)
     {
         if (GUI.Button(new Rect(100, 10, 100, 50), MuteImage))
         {
             isMuted = true;
             AudioListener.volume = 0.0F;
         }
     }
     else
     {
         if (GUI.Button(new Rect(100, 10, 100, 50), unMuteImage))
         {
             isMuted = false;
             AudioListener.volume = 1.0F;
         }
     }
 }

Try to save a value.

 void OnGUI()
 {
 
     if(PlayerPrefs.GetInt("IsMuted") == 0)
     {
         if (GUI.Button(new Rect(100, 10, 100, 50), MuteImage))
         {
             PlayerPrefs.SetInt("IsMuted", 1);
             AudioListener.volume = 0.0F;
         }
     }
     else
     {
         if (GUI.Button(new Rect(100, 10, 100, 50), unMuteImage))
         {
             PlayerPrefs.SetInt("IsMuted", 0);
             AudioListener.volume = 1.0F;
         }
     }
 }

If you want keep player settings for next restart game, you have to save this setting by:

 PlayerPrefs.Save();

You can use this function by only one call on the function:

void OnApplicationQuit() { PlayerPrefs.Save(); }

Np and good continuation !
