[SCRIPT] How to create a sound trigger area?

[flamez3]

hmmm.. What am I doing wrong?

void OnStart()
{
AddEntityCollideCallback("Player" , "ScriptArea_1" , "MonsterFunc1" , true , 1);
AddEntityCollideCallback("Player", "soundarea", "sound_func", true, 1);
}
void MonsterFunc1(string &in asParent , string &in asChild , int alState)
{
SetEntityActive("servant_grunt_1" , true);
}

void sound_func(string &in asParent, string &in asChild, int alState)
{
PlaySoundAtEntity("", "close_door.snt", "level_wood_1", 0, true);
}

The script seems fine. Is the sound not playing?
