Audio Volume, Audio Gameplay Volume not working or bug? 5.4

[Bruno.Martelli]

Followed tutorial to make Audio Volume, in 5.4. That didn’t work.
Tried again with Audio Gameplay Volume. With Audio Gameplay Volume with an Attenuation component I would assume a sound INSIDE the volume with the player inside the volume would get louder when Interior Volume is set to 1 and Exterior Volume is set to .1.

However the converse is true. To hear the sound inside the volume, when the player is inside the volume I have to do this.

I also assumed a sound on the OUTSIDE of the Audio Gameplay Volume would be quieter from INSIDE the volume. However it seems to remain at full volume.

Both sounds are WAVS, set to use same SoundClass following the guide here:

Audio Gameplay Volumes Quick Start | Unreal Engine 5.5 Documentation | Epic...

Audio Gameplay Volumes Overview | Unreal Engine 5.5 Documentation | Epic...

Any ideas? Sometimes I wish EPIC would make an example level…

Partially works if you use Metasounds- interior sounds must be spatialised else they are full loudness even outside the Audio Gameplay Volume.

Scratch that – it doesnt work followed guide here https://dev.epicgames.com/community/learning/knowledge-base/15lj/unreal-engine-audio-gameplay-volume-quickstart

Putting a sound inside the volume and a sound outside the volume, each with same SoundClass with 'Apply Ambient Volumes” checked.
Adding an ‘Attenuation Volume’ component to the 'AudioGameplayVolume ’ and tried the following settings:

With both Exterior Volume and Exterior Volume set to 0 - both sounds play at full volume
With both Exterior Volume and Exterior Volume set to 1 - both sounds play at full volume
With Exterior Volume set to 0 and interior volume set to 1 - -both sounds play at full volume
With Exterior Volume set to 1 and interior volume set to 0 -both sounds play at full volume

I just dont think it works. I wish Epic would supply a working example

Based on some comments on Reddit https://www.reddit.com/user/AnnoDelSignore13144/

I did this,
Add an AudioVolume.
Added 2 Ambient Sound Actors and assigned my SoundWaves.
One has no spatialisation the other Ambient Sound inside the volume has Attenuation(Spatialisation) inner radius slightly bigger than the AudioVolume.

Both Ambient Sounds have a SoundClass with the SoundClass property Apply Audio Volumes enabled

Both SoundWaves are set so they Loop AND under Voice Management set ‘Virtualization Mode’
to Play when silent. (else when you cant hear them, they stop playing and never play again, plus they keep playing rather than restarting)

The Audio Volume is set like this

the overall efffect is when you are outside the AudioVolume the main music is playing out, audible everywhere at full volume. As you approach the volume it sounds like outside a nightclub with muffled sound. Inside the AudioVolume, the sound quickly changes to become clear and you cant here the outside .

Unreal 5.3

AnnoDelSignore13144 said “The whole system of “audio volumes actors” attenuation only works on sound actors put in the scene as “ambient sound actors” regardless of having assigned a class with “use ambient volumes” ticked. All the other sound actors / cue apparently cannot in any way be influenced by audio volume actors.”
