Setting the Falloff Distance of a Sound Wave/Cue to 0.0 will no longer Play Sound

As the title suggests, whenever you add a Sound Cue or Wave to a level and set it's 'Falloff Distance' to 0.0 the sound will no long play.

I have attached a project to provide a simple regression test. The project was made in 4.10.2 where the issue does not occur, but if you open a copy of the project in the preview release you can reproduce the issue.

The user mentions that setting the value to any number above 0 will correct the issue....i.e. Falloff Distance to .001

1. Open attached project.
2. Press play and move forward into the Sound Wave's radius.
3. Notice the Sound plays as expected.
4. Open a copy of the project in 4.11 preview 2
5. Repeat step 2.

Expected - Sound plays when entering the radius.

Outcome - Sound does not play when entering radius.
