FMOD for Unity missing internal effect errors when building Unity Player for Win 64

Unity

Hi! I’m having issues when attempting to build a Unity project with the FMOD for Unity integration.

The Unity Player Build falls over with errors (seemingly) related to FMOD internal effects.

The errors are as follows:

Effect Highpass could not be found. Check that the project contains the correct native audio plugin libraries and that the importer settings are set up correctly.
Effect Compressor could not be found. Check that the project contains the correct native audio plugin libraries and that the importer settings are set up correctly.
Effect SFX Reverb could not be found. Check that the project contains the correct native audio plugin libraries and that the importer settings are set up correctly.
Effect Highpass Simple could not be found. Check that the project contains the correct native audio plugin libraries and that the importer settings are set up correctly.
Effect Lowpass could not be found. Check that the project contains the correct native audio plugin libraries and that the importer settings are set up correctly.
Effect Distortion could not be found. Check that the project contains the correct native audio plugin libraries and that the importer settings are set up correctly.
Effect ParamEQ could not be found. Check that the project contains the correct native audio plugin libraries and that the importer settings are set up correctly.

The errors are reported for both development and release Win64 builds. The version of Unity is 6000.0.16f1.6822.5931, and the FMOD for Unity integration package is 2.03.13, although I have also tried 2.03.06 and 2.03.14

Note that in our project, there are no FMOD Events that utilise these internal effects, but still they seem to cause the the build to fail when trying to build a Unity Player.

When I have added such effects to an FMOD Event, they seem to work fine in game playing within the Unity Editor.

Anyone encountered anything like this, or have any idea what the issue might be ?

Hi,

Thank you for sharing the version information.

The effects listed in the errors seem to be Unity Audio Mixer effects rather than FMOD effects, so it is not yet clear whether the FMOD integration is involved.

Could you please share the complete Unity Editor log from a failed build, including the stack trace around the first Effect ... could not be found error?

As a quick isolation test, could you also try temporarily re-enabling Unity’s built-in audio under Project Settings > Audio and check whether the build then succeeds? This will help determine whether disabling Unity audio is contributing to the issue.

It would also be useful to know whether the project still contains any Unity Audio Mixer assets or scripts/component that reference Unity’s built-in audio system.

Hi!

Thank you for getting back to me.

As suggested below, I did try to build with Unity Audio enabled, and that built successfully. I then found a legacy Unity Audio Mixer that was being referenced within our project. Removing that asset and re-disabling Unity Audio then led to a successful build.

Thanks again for your help and suggestions that have resolved this issue for me!
