We are having trouble producing an Android build via our Linux build agents. Builds are being produced but when executed the bank file can not be found.
```auto
BankLoadException : [FMOD] Could not load bank 'file:///android_asset/Master.strings.bank' : ERR_FILE_NOTFOUND : File not found.

```
When looking at the build logs this seems to be the underlying cause.

Unity Version: 2022.3.53f1
FMOD Version: 2.03.02
I have attempted a reimport of the Unity FMOD package.
The only libraries that appear to be included for Linux are:
- Plugins\FMOD\platforms\linux\lib\x86\_64\libfmodstudio.so
- Plugins\FMOD\platforms\linux\lib\x86\_64\libresonanceaudio.so
Are there any dependencies that may be missing on our Linux build agent? Or any indication as to what might be the root cause?

Hi,
Thank you for the information.

Yes, there should also be the `libfmodstudioL` file for Linux:
and Android:
Are you using a headless Unity to build the project? If you are checking out the repo on the build machine it may be worth checking these files have not been ignored.
