Cannot control sound distance or volume in Unity Editor

We are adding sound to our virtual world, but when we view the world in PLAY mode (using the Stanley character) none of the sound settings work. The sound is at full volume and can be heard throughout the entire world.

Are we doing something wrong, or is this the case until the world is rendered as a playable online world?

Sound is essential to our design, and this makes it very hard to build.

Thank you.

 

Have you set the Spatial Blend value to 1 to make the sound 3d and not 2d?

 

Not yet, but I'm going to!

Thank you so much, SpookyCat.
