No sound on RPG impact

[nitrox32]

I have created a new ammo from the RPG Ammo prefab.  When I fire, the sound of the firing occurs but not the impact sound.  I'm sure this is a simple matter of adding an audio clip somewhere but I can find the place to do it.  Where would that be?

Anyone?

Check the Play on Awake option of the AudioSorce on the 'particle' game object, inside the vRPGAmmo prefab
