To set up a "distant" sound to play
1.Will require an entity which plays the sound - this could be any entity but if you just want to have a sound play it could be just an invisible box entity (collision off) and script attached which just tells it to play the sound when triggered. It would need to wait for an activate if used command from a trigger.
2. A trigger object - this could be a default trigger zone using the script plrinzone activate if used - that usually works or could be the same invisible box as above with your own trigger script attached.
Default sound and trigger zones can be a bit fussy as to how and where they are used. You might as well learn how to set up your own as you will need them and the knowledge at some stage if you want to set up anything complex that the engine does not like doing by default.
