UDK adding sound

Today we went through the process of adding sounds into UDK.
Firstly we open the content browser and search for a sound node or cue. Cue's are similar to materials and nodes are similar to nodes.

I added in one around a water fall that I have in my level to support the illusion of running water.

At the beginning of my level I have a cinematic sequence right next these sound nodes so I wanted to be able to toggle them on and off. I achieved this by adding them in as ambient sound toggle-able.

To make them toggle on and off I went into kismet and created object variables for each and attached them to a toggle.
