audio - Getting a sound trigger to work -

i don't understand why sound trigger not working. have created gameobject , added audio source (on audio source have play on wake , loop checked. added sphere collider (i have is trigger checked). added script , added sound clips inspector. unity says that: "there 2 audio listeners in scene." have pretty unchecked audio listeners , still says it, doing wrong?

here @ code:

 #pragma strict   var walkaudio:audioclip;   var outcry:audioclip;    function update (){       var audio= gameobject.getcomponent(audiosource);       if(input.getbutton("horizontal") || input.getbutton("vertical"))      {           audio.play();      }      else      {           audio.pause();      }  }   function oncontrollercolliderhit (hit : controllercolliderhit)  {      var audio= gameobject.getcomponent(audiosource);       if (hit.gameobject.tag == "templefloor")      {          var groundtype = 1;          print("temple");          audio.clip=outcry;      }       else{          audio.clip=walkaudio;      }   } 

as said:

i have pretty unchecked audio listeners

the component audiolistener attached main camera must enabled. have used loadleveladditive have 2 camera , 2 audiolistener components, 1 on each of them. please make sure additive camera , other gameobject should have component disabled.

also at runtime, can search component(s) have audiolistener component attached using in hierarchy window search bar.

t:audiolistener 

this should out. double check using debug.log oncontrollercolliderhit function calls , audio.clip not null after assignment. necessary play sound in update ?

also, should move line update start function instead, due performance cost:

var audio= gameobject.getcomponent(audiosource); 

and use audio variable throughout script.
