The question is simple: Is it possible to play one of in-game ambients from here for the player via PlayerPlaySound? I didn't have much success in it as of yet.
That's not a bad question, but as far as I know they don't actually have sound IDs, since they're pretty much hard-coded into the game and they play dependent of your position and not what the server says. This would be an interesting suggestion for future SA-MP versions though.
