As the title says.
I'm new to the Creation Kit and not really into any advanced skills yet.
Is there a way to import custom sound EFFECTS, like footsteps in the far corridor or an explosion in another room, when player walks into a specific area? Google only spams about adding music and voice acting, yet nothing about sound effects themself.
My plan was to release a custom sound (I can record or get it in any format) when player gets past a point (marker maybe?) in a corridor.

So, it consists of few questions:

1) How do I import custom sound effect to creation kit?
2) How do I make a marker to trigger a sound to be player in the player's speakers (just once, not loop)?
