camera – How to make sound fx follow the player?

Here is the setup:

> KinematicBody2D (Player)
- > Camera2D
- > Node2D (SoundFX)
- - > Timer (1 sec)
- - > AudioStreamPlayer2D (Beep)

It works fine at the beginning of the scene, but the sound fades out when the player moves away. Whyt is that and how to fix it?

I have tried to make the AudioStreamPlayer2D a child of a CanvasLayer node, without success.
