Stopping audio clips

I have different buttons that play these sounds the problem is the sounds will play over each other if you click buttons really fast. I want to play a sound and if another audio is playing stop it so you only here the sound you played. Any idea? Booleans?

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class PlayCalls : MonoBehaviour {
5.  
6.     public AudioClip hailCall;
7.     public AudioClip feedCall;
8.     public AudioClip lonesomeHenCall;
9.     public AudioClip greetingCall;
10.     public AudioClip comebackCall;
11.  
12.  
13.     // Use this for initialization
14.     void Start ()
15.     {
16.    
17.    
18.    
19.    
20.    
21.    
22.    
23.     }
24.    
25.     // Update is called once per frame
26.     void Update () {
27.    
28.     }
29.  
30.  
31.  
32.     public void HailCall()
33.     {
34.  
35.  
36.             if (AudioClip(feedCall))
37.         {
38.             audio.Stop(feedCall);
39.         }
40.  
41.  
42.         audio.PlayOneShot (hailCall, 1.0f);
43.  
44.  
45.     }
46.  
47.  
48.     public void FeedCall()
49.     {
50.  
51.  
52.  
53.  
54.            
55.            
56.  
57.  
58.  
59.  
60.         audio.PlayOneShot (feedCall, 1.0f);
61.        
62.        
63.     }

 

Use audio.isPlaying to check whether a sound is currently playing. If so, stop it and play another one.

 

I tried it didn't work. I just tried this and it doesn't work either.

Code (CSharp):

1. public void HailCall()
2.     {
3.         audio.Stop ();
4.         audio.Pause ();
5.         audio.clip = hailCall;
6.         audio.Play ();
7.    
8.     }
9.  
10.  
11.     public void FeedCall()
12.     {
13.  
14.  
15.         audio.Stop ();
16.         audio.Pause ();
17.         audio.clip = feedCall;
18.         audio.Play ();
19.            
20.  
21.  
22.  
23.  
24.    
25.        
26.        
27.     }
