Creating sound on a saved ent?

I'm making an armory addon to learn how to code in gmod and the armory can be saved in the data folder and spawned automatically on map change/server restart. When spawned like this the sound doesn't play (an alarm sound when robbing as a thief) but when it is spawned through the Q-Menu it works perfectly. Any help would be appreciated.
