Audio listener not following HMD

On the Vive setup, we would like to use positional audio. We can hear scene audio in the headset, but it is not positional. The listener seems to stay at the player character root.

We tried attaching the listener to the FirstPerson camera component in this way but it didn’t work:

PlayerController->SetAudioListenerOverride(FirstPersonCameraComponent, FVector(0, 0, 0), FRotator(0, 0, 0));

Any idea how to set up the listener for VR?

TO make the audio positional, you should activate the attenuation system on the cue.
