FMod with Godot 3.5 on Linux & Windows - no audio in exported game

[loteque]

Discussed in https://github.com/utopia-rise/fmod-gdnative/discussions/133

^{Originally posted by **loteque** August 30, 2022} Godot 3.5 on Linux, fmod-gdnative plugin works in the editor. I can hear the sounds when I test the game through the Godot editor. When I export the game it has no sound. Any help much appreciated. Update: Just tested on windows and it is the same result. banks work in the editor but no sound on export.

[piiertho]

Did you added bank and sound files to exported resources in your export settings ? A log would be easier to understand what’s happening.

BTW, it makes me think we can maybe make an export plugin in order to make export of banks automatic.

I'm just headed to sleep. I will get a log when I wake up. I did added the file extensions in export settings. I am helping someone with their sound and I would guess they did not include the sound files anywhere in the "res://" path, and only included banks. I will check on all this when I wake up. thank you for the reply. I am new to fmod so everything helps.

Ok - here is the logfile: It looks like it isn't finding the fmod api module?

This seems so. What I find weird is that normally there’s no need for files ending with .13. Can you check what libraries you have in export ?

[piiertho]

Btw: here you can find discord link, https://github.com/utopia-rise/fmod-gdnative/pull/130/files So that we can discuss easily.

[loteque]

[loteque]

Yeah I am not sure what the .13 extension is about either. Also caused an issue when I was setting up the plugin.

[piiertho]

Can you try to copy the .13 files in the export directory ?

[loteque]

Do I need to reexport, after copying?

[piiertho]

No, no need

[loteque]

ok I replaced all the fmod-api modules in export directory with the modules from the plugin directory and fmod managed audio works. Modules copied over from addons into the export directory: libfmod.so libfmod.so.13 libfmodstidio.so libfmodstidio.so.13

[piiertho]

Ok seems that’s a bug from long time. We assumed it was working like on other os, but that’s not.
I found an explanation here.
We need to add versioned libraries as well in gdnlib file.
Thanks for the bug report.

[loteque]

I updated the QA discussion board with the immediate workaround.

[piiertho]

Btw, what was the problem on windows ?

[loteque]

I have not tested windows yet. When I do I will report back.

[loteque]

Windows seems fine. As far as I can tell the audio person just didn't include the audio assets in the project path. Once I copied the assets over the build works.

[GeorgeLGFreitas]

I'm experiencing the same problem but on Windows. Everything works correctly in the editor, but when I try to export, FMOD stops working, even in the demo provided in the repository.

[CedNaru]

Hello. Are you sure you are not forgetting to properly export the banks files ? They are not exported by default by Godot, so you have to add them manually in the export menu. The code shouldn't behave differently being a debug or release build and so far most sound issues reported were because of a faulty export. Otherwise without more information, it will be hard to figure out the issue. Can you check if your exported game contains the bank files (and not the project itself)?
