[Import] special effect doesn't make sound when imported

[hemmedo]

I'm using doomdeath model with some particle emitters edited(didn't do anything to sound node, just recoloring thats all). In my spell when this effect occurs there's no sound but when I use original doomdeath model from its mpq path it works and makes sound perfectly...what's the problem here?

Yeah I could just use another special effect but this problem is so stupid I wanna fix it...thanks for the help.
