Hi,
It seems that I have a mix of multiple problems when I try to integrate FMod to the project, and I think I miss something during the process. For start, I both tried with 2.03 and 2.02 versions of both FMod studio and the integrations plugins for unreal 5.3.
First, validate FMod seems to not work as I get “Failed to load banks” pop up, despite having the uasset banks files correctly generated.
Then, I cannot play the sound of the event nor I have any info displayed, but it works fine in both editor and when packaged with the FModAmbientSound in the scene.
Also, I have this warning flooding my log:
C:\buildagent2\work\c1c3f17eb167c494\studio\_api\src\fmod\_objectlookup.h(125) - Lookup failed for EventModel: {346e521e-d600-4c21-b870-cffb7bb2de63}
Overall I’m confused, as everything seems to work where it not supposed to and I wonder if it’ll break later in development, and i would like to prevent any future problem by fixing these errors. So if someone has some insight to solve these warnings, I would be pleased!

Hi,
You’ve run into a known issue with 2.02.28/2.03.07, where banks aren’t loaded properly for auditioning in the UE editor. A fix is currently scheduled for our next release. For now, downgrading to the previous version of FMOD (2.02.27 or 2.03.06) should work around the issue.
