Unreal 5.0.2. FMOD version is 2.02.07 - Totally silent during PIE

Encountering this issue in Unreal 5.0.2. FMOD version is 2.02.07
Audio plays if opening the event (pressing the play button) in the content browser but totally silent during PIE (ambient sounds, blueprint calls and even 2D events).

Project audio worked perfectly fine during PIE in 4.26. No changes to plugin settings or configuration.

Will produce a video to showcase this issue shortly.

Unfortunately adding an editor platform didn’t fix this either.
AUTODETECT or WASAPI still result in no audio during PIE but it works fine in the content browser.
Video attached:

No ASIO warnings or errors either in the log.


We do not currently support Unreal 5.0.2, but it should work if you recompile the plugin. Can you please try going through the steps in the Compiling the plugin section of the User Guide?
I have tested with 2.02.07 after recompiling the plugin and everything seems to be working correctly. If that doesn’t work for you, can you please do the following:

  • Go to Project Settings>Plugins>FMOD Studio>Advanced>Logging Level and set it to “LEVEL LOG”
  • Play in editor
  • Share the entire log output here

I have recompiled the same plugin by taking help from the suggested user guide. Everything is working correctly for me.

Thanks Jeff, will do so today and get back to you.
Really appreciate the assistance!

Recompiled as instructed. That worked fine.

Tried again with the recompiled plugin and unfortunately no such luck. Log attached:

The events do exist and play in editor just fine, but from the log it seems a lookup of some sorts is failing and a DSP source is missing.

I think this may be because Resonance is included with UE5 instead. I’ll re set up the plugin and ensure the .dll is there and report back.

EDIT: Can confirm I think the cause of this is Resonance.

This is especially strange as no paramemters have changed it’s a direct copy of the FMOD folder from the old 4.26 project to the the new 5.02 test project.

FURTHER EDIT: After readin this Resonance Audio - Installing the Latest Resonance Audio Plugin Version From GitHub it seems it may be necessary to get our sound team to recompile the banks with the new binaries? Not sure exactly what this entails.

Hope this helps you folks figure out the cause of all this!

Can confirm that rebuilding banks in the latest version of FMOD studio fixed this issue!

For future reference, if you want to use any UE4.26/27 banks in UE5.0.2 you must rebuild the banks in the latest version of FMOD studio and the plugin as instructed above.

Appreciate everyones assistance. Marking as solved.
