Hello, we are trying to build for IOS and getting no sound. In the Log we found that the bank file have to be missing, because no events can be found? EventNotFoundException: FMOD Studio event not found ‘event:/Music/AmbientMain’ at GooglePlayDownloader.GetExpansionFilePath () [0x00000] in :0 at FMODUnity.RuntimeManager.CreateInstance (System.String path) [0x00000] in :0 at FMOD\_PlayOnEnable.OnEnable () [0x00000] in :0 (Filename: currently not available on il2cpp Line: -1) In the Editor the sounds are played without problems. The Android build is working fine. We are using Unity 5.3.1f and the latest FMOD version. Thank you for your help! Edit: Why FMOD is invoking the GooglePlayDownloader on playing sounds? ---

FMOD doesn’t use GooglePlayDownloader at any shape or form. Unity runtime is generating incorrect callstack, perhaps try a development/debugging build. Can you post any error messages from the bank loading stage. ---

Thank you for your fast response. I get following debug output: ``` FMOD Studio: Creating runtime system instance FMODUnity.RuntimeManager:Initialiase(Boolean) FMODUnity.RuntimeManager:get_Instance() FMODUnity.RuntimeManager:PathToGUID(String) FMODUnity.RuntimeManager:CreateInstance(String) FMOD_PlayOnEnable:OnEnable() (Filename: /Users/builduser/buildslave/unity/build/artifacts/generated/common/runtime/UnityEngineDebugBindings.gen.cpp Line: 37) FMOD Studio: Device iPod7,1 classed as MobileLow FMODUnity.RuntimeUtils:GetCurrentPlatform() FMODUnity.RuntimeManager:Initialiase(Boolean) FMODUnity.RuntimeManager:get_Instance() FMODUnity.RuntimeManager:PathToGUID(String) FMODUnity.RuntimeManager:CreateInstance(String) FMOD_PlayOnEnable:OnEnable() (Filename: /Users/builduser/buildslave/unity/build/artifacts/generated/common/runtime/UnityEngineDebugBindings.gen.cpp Line: 37) EventNotFoundException: FMOD Studio event not found 'event:/Music/AmbientMain' at GooglePlayDownloader.GetExpansionFilePath () [0x00000] in :0 at FMODUnity.RuntimeManager.CreateInstance (System.String path) [0x00000] in :0 at FMOD_PlayOnEnable.OnEnable () [0x00000] in :0 (Filename: currently not available on il2cpp Line: -1) ``` * * * EDIT: I have removed the GooglePlayDownloader class for IOS Builds, now I am getting this: ``` EventNotFoundException: FMOD Studio event not found 'event:/Music/AmbientMain' at FMODUnity.OneshotList.SetParameterValue (System.String name, Single value) [0x00000] in :0 at FMODUnity.RuntimeManager.CreateInstance (System.String path) [0x00000] in :0 at FMOD_PlayOnEnable.OnEnable () [0x00000] in :0 (Filename: currently not available on il2cpp Line: -1) ``` ---

Now I have added a manual bank load for the master bank and I am getting following error: BankLoadException: FMOD Studio could not load bank ‘/var/mobile/Containers/Bundle/Application/DD7F6221-18D2-4F4E-A51F-D658D17DF130/ATAK.app/Data/Raw/Master Bank.bank’ : ERR\_FILE\_BAD : Error loading file. ---

Updating to Unity 5.3.2 has resolved the problem. I have no idea about the reason… ---

> [@](#): > > Updating to Unity 5.3.2 has resolved the problem. I have no idea about the reason… My best guess is “(760943) - IL2CPP: Do not incorrectly free blittable arrays marshaled as [In,Out] parameters” meant that passing strings to FMOD resulted in getting garbage bank file names and event names. “(754539) - iOS/IL2CPP: Correct stack traces in exception messages, which could sometimes miss managed frames.” is why none of your stack traces made any sense.
