Audio Doesn't Work in Packaging and Launch Mode - FMOD 2.00.08 | UE4.24.3

Unreal Engine
1

Hi Everyone, I got this issue that seems to have no solutions.

I did the following steps:

  • Create a new Unreal Project with the third person template
  • Add the FMOD plugin folder in /Game/Plugins
  • Build an FMOD Project in /Game/Content/FMOD
  • Place an FMOD Ambience Sound in my character and load the correct event from the bank

All work when I play in the editor mode. When I try to launch it in the editor or build a package, all sounds disappear and I got these errors from the log:

I tried (as I found in other topics around the internet):

  • Delete the plugin section in the .uproject file opening it with a text editor
  • Disable the Event Driven Loader
  • Modify the Modules section in the .dylib files in the FMOD plugin
  • Other things that now I don’t remember exactly

Sorry, but I’m a little bit desperate about this. I and my team are stuck on this problem and I can’t find a solution, anyone can help us?

Thank you for the answer, hoping for good

HI Kranyos!

  1. Did you add a FMOD directory inside Project settings->packaging->Additional assets directories to Cook ?
  2. Inside Project settings->FMOD studio is all ok with Bank output directory and no warnings?
  3. Did you enable plugin at Edit->Plugins ?
  4. Did you build as C++ your project before shipping? (you should generate .sln and build project from Visual Studio)

You should only have the built bank folders in this directory, not an entire FMOD Studio Project.

@i4ugui has a number of good ideas to check.
