We had to update our FMOD integration to 1.10.13.
I deleted the old FMODStudio plugin from the project and replaced it with the new one.
Deleted the FMOD folder from the Content library and rebuilt the whole project again.
Nothing else has changed otherwise.
In editor everything is fine, not getting any plugin related errors or warnings.
However there are no FMOD sounds in the packaged version, only inbuilt unreal sounds.
No idea where to go from here.
Also copied all the plugin dlls and plugins.txt to the new plugin folder.
Could not get 1.10.13 to work, I suspect it was caused by some corrupted plugin files. However downgrading to 1.10.12 did the job.
What version of UE4 are you using?
I’m not having any issue getting it to work, if you have any logs from issue I may be able to help figure out the problem.
I’ve been tracking down a similar issue which was caused by running the 4.22 version of FMOD against UE4 4.21. Switching to the 4.21 version fixed it for us.
