"Tornado" sound problem

[Xantog 10]

I am trying to get the old OFP Tornado script by "AlexeyZ" in Arma 2 OA to work, with success, but not the sound of the moving tornado!

No sound with the original script:

^{_sm = _this select 0}

^#start

^{_sm say "tornado"}

^~9.2

^{?(stop_sm or (_sm distance player >10000)) : exit}

^{goto "start"}

^exit

I placed a "EmptyHeli" object in intervals to "_sm" and let the "Heli" object saying the sound!

This time it repeats the sound 3-4 times but then no sound:

^{_sm = _this select 0}

^#start

^{H setpos getpos _sm}

^~0.5

^{H say "tornado"}

^~9.5

^{?(stop_sm or (_sm distance player >10000)) : exit}

^{goto "start"}

^exit

I know, I am not the best scripter, but has anyone an idea, what could help!

Thanks!
