Just dealt with same problem. Not sure what causes but I made the same observation. It is related to AudioSource.PlayClipAtPoint() once replaced with audio.PlayOneShot() everything seems to be fine.

I wrote a post about it if you want to check for more details and code examples.

using UnityEngine; using System.Collections;

public class PortaoSaidaSomScript : MonoBehaviour { public bool tocar; public AudioClip PortaoAudio; // Use this for initialization void Start () { tocar = false; }

void Update () { if (!tocar) { toca(); tocar=true; } } void toca() { audio.PlayOneShot(PortaoAudio); } }

having the same problem on Unity 3.4

Figured out what may be your problem. If you are doing a 2D game, make sure that all your audio files have the 3D Sound checkbox turned off.

You might want to check the priority of your sounds. I haven't played with it too much, but I know that depending on the priority's of the sounds playing Unity will cut some sounds out if there are too many playing at once. It's like when you have too many point lights in the scene, and depending on the quality level, Unity will stop rendering certain point lights to save on memory.

yup, just looked it up:
