I’m working in a project of archviz, and I was create a widget for menu when we can turn on and off the lights, sound etc.
On simulation of blueprint everything work’s perfectly, bu when I make te pack of file and exec the buttons of lights work, but the sound no.
My procees was the same for lights and sound: create a variant set, and was used the node SWITCH ON VARIANT BY NAME for on e off.

Some one ever had this problem?

This could be caused by a variety of factors, including a problem with the sound asset itself or an issue with the way the sound is being played in the blueprint.

Here are a few things you can try to troubleshoot the problem:

  • Make sure that the sound asset is properly imported into your project and that it is located in the correct directory.
  • Check the sound asset’s properties in the Unreal Engine Content Browser to ensure that the sound is set to play correctly.
  • Check the blueprint logic that controls the sound, make sure that the sound is being played at the correct time and with the correct settings.
  • Check the sound’s volume in the Blueprint, make sure that it’s not muted or has low volume.
  • Try to test the sound in the editor with the play button, to check if the problem is related to the packaging process.
