Warning: "Can not play a disabled audio source"

Hello everyone! I recently got Unity 3.5 and I’m having an error everytime I try to play an AudioSource. The sound is a 2D sound and is in a prefab. Upon activating the sound I get the error(warning); “Can not play a disabled audio source”. However the sound still plays perfectly. Any ideas? Can I disable the warning?
EDIT: Here’s the snip’it of code with the audio

if(!reloading && Input.GetButtonDown("Reload") && currentClip < clipSize && currentExtraAmmo > 0) {
	reloading = true;
	gunAnimation.CrossFade("reload");
	reloadSound.Play();
}
if(!reloading && Input.GetButtonDown("Fire1") && currentClip == 0 && currentExtraAmmo > 0) {
	reloading = true;
	gunAnimation.CrossFade("reload");
	reloadSound.Play();
}

Thanks!

Try adding calls to Debug.Log next to the code that a) plays the sound, and b) enables the audio source. Maybe they aren’t occurring in the order you think they are.
