Chapter text with sound clip

I was wondering how to put in the text that comes up in every half-life game when you start a chapter, with that sound clip. I’ve tried env_message but it doesn’t work. I have a game_text entity that works fine except for the sound. Any help?

For the sound you can use an ambient_generic entity and check the “Play everywhere” flag.

Chapter Title, Map->Map Properties.

I did this but the text won’t show on the screen, is there some entity I need to add for this to happen?

Game_text + ambient_generic entities, fired at map start (?) using a logic_auto, or if you wanna trigger it, you would use something like a button or trigger brush.
