UMG Animation sounds do not play in PIE

Sounds are not playing in PIE for UMG animations.

The sounds will play fine if you launch on or play in Standalone game

1. Create a new UMG Widget
2. Create a new UMG Animation within that widget that contains and audio track
3. Wire the animation to play on Event Construct
4. Open the level blueprint
5. On Event BeginPlay create the widget and add to the viewport
6. Compile and save everything
7. PIE

Result: Sound does not play

Expected: Sound should play when the widget is created and added to the screen in PIE
