plugin not working on Quest when building from Windows

[jinpavg]

After building an android build of the plugin on macOS, and then building a Quest game on macOS that includes that plugin, a user reports that the plugin works on Quest, loaded either as a "custom filter," or as a plugin effect loaded on an AudioMixer. However, when building the Quest game from a Windows machine, the AudioMixer-loaded version of the plugin no longer works (the user reports that the filter version still works).

I can reproduce with slightly different variables -- if I build the plugin for android on Windows (using Ninja), the plugin builds successfully but I don't hear it working as a filter or mixer-loaded plugin on the Quest. The Windows version works fine in the Unity Editor, and other audio (non-RNBO) works fine on the Quest.

@jinpavg just to be sure, when you built the plugin on windows, did you supply this option -DANDROID_CPP_FEATURES=exceptions

Ah, I tried both with and without, with the same results so far.

I just built and ran successfully from my windows machine:
I'm using 'Ninja' to build.

cmake .. -G "Ninja" -DANDROID_PLATFORM=29 -DANDROID_ABI=arm64-v8a -DCMAKE_TOOLCHAIN_FILE="C:\Program Files\Unity\Hub\Editor\2021.3.23f1\Editor\Data\PlaybackEngines\AndroidPlayer\NDK\build\cmake/android.toolchain.cmake" -DRNBO_EXPORT_DIR="C:\Users\xnor\Documents\export\simple-freq-param\" -DRNBO_CPP_DIR="C:\Users\xnor\Documents\export\simple-freq-param\rnbo" -DPLUGIN_NAME="SimpleFreqParam" -DANDROID_CPP_FEATURES=exceptions
cmake --build .

then I copied my native windows plugin into correct folder:

PS C:\Users\xnor\dev\rnbo.unity.audioplugin\build> ls .\SimpleFreqParam\Assets\Plugins\Windows\


    Directory: C:\Users\xnor\dev\rnbo.unity.audioplugin\build\SimpleFreqParam\Assets\Plugins\Windows

I wonder if there is something going on with signatures when you build the android plugin on mac and then try to deploy to android from windows?

I'm using Unity Editor version 2021.3.23f1, I used the VR template and these instructions for setting it up further: https://www.circuitstream.com/blog/oculus-quest-2-setup

in powershell, in the unity plugin project directory

cd .\build\ 
cmake .. -G "Ninja" -DANDROID_PLATFORM=29 -DANDROID_ABI=arm64-v8a -DCMAKE_TOOLCHAIN_FILE="C:\Program Files\Unity\Hub\Editor\2021.3.23f1\Editor\Data\PlaybackEngines\AndroidPlayer\NDK\build\cmake/android.toolchain.cmake" -DRNBO_EXPORT_DIR="C:\Users\xnor\Documents\export\simple-freq-param\" -DRNBO_CPP_DIR="C:\Users\xnor\Documents\export\simple-freq-param\rnbo" -DPLUGIN_NAME="SimpleFreqParam" -DANDROID_CPP_FEATURES=exceptions
cmake --build .
cd ..
mkdir build-windows
cd build-windows
cmake .. -G "Visual Studio 19" -DRNBO_EXPORT_DIR="C:\Users\xnor\Documents\export\simple-freq-param\" -DRNBO_CPP_DIR="C:\Users\xnor\Documents\export\simple-freq-param\rnbo" -DPLUGIN_NAME="SimpleFreqParam"
cmake --build .
Copy-Item -Path .\SimpleFreqParam\Assets\Plugins\Windows -Destination ..\build\SimpleFreqParam\Assets\Plugins\ -Recurse

In my Unity project, I add the RNBOTypes package and also SimpleFreqParam by path (I didn't move them), I also edited the "Audio" project settings and setup the occulus spacializer, then I created a mixer and then found an object in the scene, added an audio source to it, selected an audio file (not sure if i needed to do that), then set the mixer for the source to the mixer I just created, finally I added my plugin to the top of the mixer I just created and deployed to my occulus via 'Build and Run'

I suspect the issue some people are seeing is with a mismatch of player and plugin architectures.. the plugin is being built for ARM64, make sure that your player is also targeting ARM64

closing this for now, i think this is working if folks set this up as described above
