FMOD Unity Android Build: Some events not playing, failed to open master.bank

zaqwertu · August 15, 2021, 8:23pm

Hello,

We are currently using FMOD Studio and Unity integration version 2.01.11

We are having android-build specific errors where sounds are silent when triggered. These errors do not occur in the windows build of the game. This issue is not occuring in every scene, none of the messages below are printed into the console when all sounds are playing correctly.

Here are some of the messages being printed into the android log of a development build, would appreciate any guidance on how to fix this.

Best,
Zach

Are you using split binaries with a separate apk and obb file? The 76 error indicates that the resource isn’t loaded, and the 18 error indicates the file wasn’t found. Perhaps you could try loading the scene and banks asynchronously- we have an example in the scripting docs.

zaqwertu · August 22, 2021, 12:38am

Hey Jeff!
Thanks for the response.

I tried loading the banks asynchronously via the coding example, it works for loading the banks but it did not solve my issue. I’ve added the console messages again, I’m wondering why it’s logging "Could not open 'Master.bank' from the asset manager." I checked the banks with a call to FMODUnity.RuntimeManager.HasBankLoaded(bankName); and they all return true.

I might need a little more context on your setup to figure out what’s going on here. Can you please let me know:

Are you using split binaries in Unity’s Android Player Settings?
Are you using Streaming Assets or Asset Bundles in the FMOD Integration Settings?
In the Build preferences of FMOD Studio, do you have “Build metadata and assets to a single bank” selected or one of the other options?

zaqwertu · August 24, 2021, 12:50am

Thanks for the follow up,

We weren’t using split binaries, switching to split binaries in the android player settings appears to have fixed the issue. I can mark this as a solution if I don’t find any issues after some more testing.
We are using streaming assets in the FMOD settings
In FMOD the current selection is “Build metadata and assets to a single bank”

jeff_fmod · August 25, 2021, 12:52am

Glad to hear that’s working. Thanks for confirming your solution!
