Firing stand animation sound only once

[darwin]

EDIT: Nevermind, I found it.

I am using a "laser" unit as a projectile in my map. The world editor treats it as a "unit", etc., but I move it using triggers and detect targets around it until it hits one, then I kill it and do damage.

I want this laser to play a sound when it fires. This happens rapidly, so I can't trigger the sound. I know how to open up a model in War3ModelEditor and attach sounds. The model has a birth, stand and death animation.

Here is my problem:

Birth: the birth animation does not play when I make the unit. I don't know why, but when I create the unit at a place it does not play this sound. Therefore, the birth animation part is out.

Stand: when I attach a sound to the stand animation, it repeats over and over again so one shot sounds like 4. These units don't live long, just 2.5 seconds, but it still manages to play the sound 4 times.

How do I get the unit to play the sound only once?

Thank you,

Darwin

EDIT: I changed the "stand" animation to "non-looping" and it solved it.
