Problem --- Cannot create FMOD::Sound instance for resource in Webgl Build/Editor

Hi everyone, i have a Audio problem in Webgl build. I'm not sure if anyone else have seen this problem.

I'm making a AudioCache to save AudioClip loaded from Assetbundle. After i use WWW to download Assetbundle from Server and ready to use assetbundle.LoadAssetAsync to get AudioClip, this error msg come.

The code is here

Code (CSharp):

1. LoadedAssetBundle bundle = AssetManager.Instance.GetLoadedAssetBundle(_sAssetBundleName, out _sDownloadingError);
2.         if (bundle != null)
3.         {
4.             _request = bundle.assetBundle.LoadAssetAsync(_sAssetName, _type);
5.             return false;
6.         }

The sound file format is mp3, wav and ogg. I have test these sounds by using them in AudioSource directly, everything is ok. But afer bundled these can not be use... by the way, bundle code is paste on below:

Code (CSharp):

1. [MenuItem("Ozovr/BuildAssetBundle/TargetPlatform/WebGL")]
2.     private static void BuildAssetBundleForWebGL()
3.     {
4.         BuildPipeline.BuildAssetBundles("Assets/AssetBundles/Webgl",
5.             BuildAssetBundleOptions.CollectDependencies | BuildAssetBundleOptions.DeterministicAssetBundle,
6.             BuildTarget.WebGL);
7.     }
8.  

And the AudioClip setting is here:


----------
I buid this project to webgl and sounds can play.... but why in editor mode have this problem?

 

I have change “Load In Background” to true, and nothing error logged, but the AudioClip's isReadyToPlay always false

 

I have solved this problem, Unity3d editor mode don't support Webgl AudioSource Assetbundle.... I create a Standalone type Assetbundle and load it, everything is ok... i don't know how unity3d bundle audiosources with webgl mode....

 

I also solved my issue with this, by simply changing the import setting on the offending audio file, and "poof" error gone.

 

changed the import setting to what? can you be more explicit please? tnx

 

I just changed the settings to this, and applied, and it fixed itself.

 

I also have this problem when trying to build for iOS or Android on 5.3.1f. 5.2 builds without any problems (except for Cloud Build which crashes on the same FMOD error, for some reason). The build just breaks on some audio files. I had a longer explanation but the forum thinks it's spam no matter how I edit it and I don't have time to spare right now, so I'm just throwing this out there in hopes of more information. Googling gives more posts with the same issue.

 

Thanks all, this also solved my issue I was having where the sounds clips were giving the FMOD error after I unloaded my asset bundle after unpacking it, but worked fine if I left the bundle loaded. Turning on the "Preload Audio Data" checkbox was what fixed it for me.

 

I am also having some issues with Unity Audio While trying to build my IOS App
It crashes immediately on load
But if I disable Unity Audio in project Settings App runes fine.

I am a beginner in unity development. and not an coder so using Fungus ..
Can any one please guide me .. what should I do to make may App Working With Audio.

getting bellow mentioned Error massage in Xcode before disabling Unity Audio

Thanks for any help!

 

I checked 'Load in Background' on the audio clips and this solved it.

 

From Where can i check them?

 

You can check it from where the audio file is on the Project. Load in Background did not work for me. I also turned on "Force to Mono". Then solved.

 

For me only the longer audio file was a problem so I tried to lower it's quality.
The solution was to lower the sound clip QUALITY below 100% inside the import settings.

 

UnityWebRequest www = UnityWebRequestMultimedia.GetAudioClip(filepath+ audiofileName+".mp3", AudioType.MPEG)) ..change the audio type to the audio type like wav or mpeg or likewise
