Custom Sound Cue only plays for a fraction of a second when ending game session – Epic built-in cues work normally

Summary

Custom Sound Cues created from imported audio do not play during gameplay or Live Edit. The audio only becomes briefly audible for a fraction of a second at the exact moment the game session is ended. Built-in Epic Sound Cues work correctly under the same conditions.

What Type of Bug are you experiencing?

Audio

Steps to Reproduce

  1. Import a custom audio file and create a Sound Cue from it (Wave Player → Looping enabled, properly connected to Output).

  2. Confirm the Sound Cue is correctly set up (Attenuation and spatialization disabled inside the Cue).

  3. Place an Audio Player Device (or Radio Device) and assign the custom Sound Cue.

  4. Configure the device with:
    Enabled During Phase = Always
    Enable Volume Attenuation = Off
    Enable Spatialization = Off
    Restart Audio when Activated = Off
    Play Location = Device
    Can be Heard By = Everyone

  5. Launch Live Edit or publish the island as private and start the game.

  6. Trigger the audio (Auto Play, Verse Play(), or event binding).

Expected Result

Custom Sound Cue plays normally and continuously (or according to the device settings), just like built-in Epic Sound Cues.

Observed Result

  • Complete silence during Live Edit and during gameplay on a published private island.
  • Audio becomes briefly audible only for a fraction of a second when game is ended.
  • Built-in Epic Sound Cues play correctly with the exact same device settings and setup.

Platform(s)

PC (UEFN)

Additional Notes

  • Problem occurs both in Live Edit and on published private islands.
  • Changing Virtualization Mode, attenuation, spatialization, Restart settings, Play Location, and Enabled During Phase does not fix the issue.
  • Creating a brand-new Audio Player / Radio Device and a brand-new Sound Cue does not help.
  • Epic’s own Sound Cues work without any issues under identical conditions.

Hi @KamilJa Is this still happening after today’s update? If yes, could we get your island code/project ID, where the issue is happening, and your logs?

You can DM me your project ID/Island code if you’d like.
