Description

Found while writing EngineTests for [Link Removed]. Appears to work the other way around (using Exterior volume and having the sound inside and the listener outside to start).

This also occurs when changing Reverb settings on a Reverb component , with Submix Send Settings and Submix Override when the listener position is set to Inside the volume , with a Filter component when setting Exterior LPF . If a player spawns inside the component, the settings do not take unless the player exits and reenters the component.

I have a change I can shelf for testing in EngineTest if that's easier than recreating, as I was writing it when I encountered this.

Video example – Player Start is inside the volume on PIE. [Link Removed] Ignore slightly weird sounding audio, recording remote desktop audio gets weird sometimes.

Blueprint for ref:
[Link Removed]

Steps to Reproduce

1) Launch any project. Enable Audio Gameplay Volumes plugin if it's not.
2) Create a Blueprint Actor
3) Add an AudioGameplayVolume (VolumeProxy) component
4) Set Proxy to AGV Primative Proxy
5) Add an AttenuationVolume component
6) Add a mesh (ex a Cube). Size it to be large enough to have the player start be inside it.
7) Select the Mesh and set the Collision parameters in the Details panel.

  • Disable Collision > Generate Overlap Events.
  • Set Collision > Can Character Step Up On to No.
  • Set Collision > Presets to Custom.
  • Under Collision > Collision Presets > Collision Responses, select Overlap. This selects - Overlap for all response types.

8) Add the Blueprint to a level
9) On EventBeginPlay set Exterior Volume to 0.0
10 ) Add the Blueprint to your level
11) Move player start so it's inside the mesh when the level starts
12) Add a sound outside the mesh. The sound *must* have a Sound Class on it with *Apply Ambient Volumes* enabled
13) PIE

Expected Result:
The sound goes silent

Actual Result:
The sound plays at full volume unless the player exists and reenters the volume.
