Multiple PlayOneShot bug

Hi! I have this script attached to my main camera:

 public class soundCamera : MonoBehaviour {
     public AudioClip shot;
     public AudioSource source;
 
     public static void shotSound() {
         source.PlayOneShot (shot);
         }
     }

When I need the "shot" sound to play, I can call shotSound() from another script:

 soundCamera.shotSound()

It works great until I try to play a lot of sound in a row. Then it just stops playing the AudioClips. If I wait several seconds, it works again.

I want a lot of sound feedback in my game, so I'll have to fix this issue.

Thanks in advance!
