Reproduced 10/10 times. Issue also occurs in //UE5/Release-5.0 - CL 20979098 Binary. Confirmed NOT a Regression.

None of these settings seemed to have any effect:

  • Preselect at Level Load (Random node)
  • Should Exclude from Branch Culling (Random node)
  • Prime on Load (Output Node)
  • Disable Random Branch Culling (Output Node)
  • Maximum Branches on Random SoundCue nodes (Project Settings)
Steps to Reproduce
  1. Get 5 sound effects and import them into your project. Also import a sound effect that signifies the end of a sound cycle.
  2. Create a new Sound Cue
  3. In the Sound Cue node editor, import all of the sound effects, including the "end cycle" sound effect.
  4. Insert a Concatenator with 6 inputs, and a Randomiser with 5 inputs. 
  5. Connect the Randomiser to the first 5 inputs of the Concatenator, and the "end cycle" sound effect in the sixth.
  6. Connect all of the other sound effects to the Randomiser's 5 inputs.
  7. Connect the Concatenator to a Loop node, then connect the Loop node to the Output node.
  8. Import the Sound Cue into the game space, making sure the Sound cue is set to automatically play when loading and playing the game. Attenuation may be turned off for convenience.
  9. Set the Play Mode to "Standalone Game" and play the game.

Actual Results: Each time the game is loaded, the first sound listed in the Random Node is always the first sound that is played by the sound cue.

Expected Results: The first sound played is randomly chosen between the 5 inputs.
