Stop audiosource clip from playing

Unfortunately, I don't think you can stop PlayClipAtPoint unless you find it as a gameObject and destroy it. Aldo has covered this topic here : http://answers.unity3d.com/questions/316575/adjust-properties-of-audiosource-created-with-play.html

Is there any reason you have to use PlayClipAtPoint and not a permanent audioSource that you just use audio.Stop(); and change the audioClip ?

Edit :

• Create an empty GameObject > Create empty

• Attach the Component Audio > Audio Source

• un-tick Play on Awake

• Attach the below script, then drop sounds in the Inspector.

• press play

• hit 1 or 2 . The audio should stop, change clip and play the selected sound.

Script :

 #pragma strict
 
 var clip1 : AudioClip;
 var clip2 : AudioClip;
 
 function Start() 
 {
     audio.Stop(); // just incase PlayOnAwake is ticked
 }
 
 function Update() 
 {
     if ( Input.GetKeyDown(KeyCode.Alpha1) )
     {
         audio.Stop();
         audio.clip = clip1;
         audio.Play();
     }
     
     if ( Input.GetKeyDown(KeyCode.Alpha2) )
     {
         audio.Stop();
         audio.clip = clip2;
         audio.Play();
     }
 }

Here is a video on audio source : http://www.unity3dstudent.com/2010/07/beginner-b10-audio-basics/

If you use this method, just make the empty gameObject with the audio as a child of your character, then everywhere the character goes, the sound follows. PlayClipAtPoint is usually to play a ricochet sound at the point the bullet hit an object, or other similar scenarios where you only want one sound at a position to play once only (then gets destroyed, pretty much the same as PlayOneShot).
