Can AudioSources not play sound when their methods are called by a UnityEvent .Invoke()?

I have an object with an AudioSource and it's playback methods work fine with calls from other scripts, Button OnClick() events. However, when I try to make a public UnityEvent that can do the same and be set in the inspector, the method does get called and it will do everything else but the sound never happens. I'm not getting any errors either.

 

I had to implement the following work around:

Code (CSharp):

1.     public class SoundEffectsManager : MonoBehaviour
2.     {
3.         public AudioSource aSource;
4.         public AudioClip clip01;
5.         public bool play = false;
6.  
7.         private void Update()
8.         {
9.             if (play)
10.             {
11.                 play = false;
12.  
13.                 aSource.PlayOneShot(clip01);                  
14.             }
15.         }
16.  
17.         // Call this from the public UnityEvent in the inspector
18.         public void SetClipAndPlay( AudioClip clip)
19.         {
20.             clip01 = clip;
21.             play = true;
22.         }
23.  
24.         // this won't work if you call it from the public UnityEvent
25.         public void PlaySFX( AudioClip clip)
26.         {
27.             print("Playing: " + clip); // this appears in the console though
28.             aSource.PlayOneShot(clip);
29.         }
30.     }

Actually, this stopped working as well. It's weird enough to just be a bug I think.

 

You should report that as a bug!

 

Ah, thanks! I was almost certain it should work that way.

 

I put together a sample of my problem and sent it in. I'd have to check if the problem persists in 2017.4 though, I'm still on .3.
