I'm trying to have a room the player steps into have its own ambient sound. not place a script_struct and have it loop. for example the zm_giant.map
they have trigger_multiple brush textured with a sound_trigger texture and a targetname   ambient_package and script_ambientroom  factory_largeroom.
when i tried this it didn't work also watched this video by  UGO aka Wakka on Tutorial 6 - Adding Sounds - Ambient - Reverb - Bumps, watched like a bunch of times
and still couldn't get it to work!! please help me somebody! I know someone has this working.
