Syncing FPS Firing Sound over network via RPC {PHOTON}

Hello Guys , I'm having troubles with @RPC to sync My sounds on the network . I want to Sync the Firing Sound , so the other players can hear it .

Here is my sound code :

     var drawAnim : String = "";             // animation of taking out weapon.
     var drawReturnAnim : String = "";        // putting back weapon (playing draw animation backwards)
     var fireAnim : String = "";                
     var reloadAnim : String = "";
     var fireEmptyAnim : String = "";      //if you dont have this specific animation, you can use your "Fire" animation. 
     var idleAnim : String = "";
     var drawAnimSpeed : float = 1.0;
     var drawReturnSpeed : float = 2.0;
     var reloadAnimSpeed : float = 1.0;
     var fireSound : AudioClip;
     var soundGO : GameObject;
     var drawSound : AudioClip;
     var reloadSound : AudioClip;
     var outOfAmmo : AudioClip;
     
     //Shotgun Animations
     var startReload : String = "StartReload";
     var insertBullet : String = "Insert";
     var endReload : String = "AfterReload";
     var SGinsert : AudioClip;
     var SGpump : AudioClip;
     var weaponScript : WeaponScript;
     //Only for Crossbow
     var idleLoadedAnim : String = "";
     
     var audioShellEject : AudioClip;
     private var step : boolean = true;
     
     function OnEnable () {
     step = true;
 }
 
 function Start(){
     //animation.wrapMode = WrapMode.Once;
     if(idleAnim != "") animation[idleAnim].wrapMode = WrapMode.Loop;
     if(idleLoadedAnim != "") animation[idleLoadedAnim].wrapMode = WrapMode.Loop;
     if(weaponScript.typeOfFireMode == fireMode.Shotgun){
         animation[endReload].layer = 5;
     }
 }
 
 function Update(){
     if(idleAnim != ""){
         if(!animation.isPlaying){

Just tell me how . Any Help will be highly appreciated !

Thanks in Advance!
