This issue apparently, after couple hours of testing, occurs when updating single shots, there might be something we have done in the code or in the soundbank. We had Fmod 1.10 previously and did not had any problems other than game crashing on android due mutex thread issue which this update was supposed to help with. Repro is possible with just running the game and the game just crashing in random points.

Link to image for xcode part where the crashing is happening: [https://ibb.co/CnzYfc8](https://ibb.co/CnzYfc8)

Also memory read error in fmod update thread:

</div>

Issue started after we updated from version 1.10 to the latest 2.00.09, update was smooth without problems, no code changed were made and the sound banks were builded again using the same updated version of Fmod

Could you try reproducing the crash on Android using the logging version of FMOD? It will send useful debug information to LogCat and also provide better crash callstacks than the release version.

Will start debugging now with logging version of FMOD.

Sorry for the messy copy paste with those logs and thank you for editing them. Is there something changed the way single shots are handled from 1.10 to 2.00.09? We did not touch the logic when we updated to the 2.00.09 because of the android 9 and 10 crashing issue. Seems to be the case that it tries to destroy something from the playback system and fails and causes the crash, maybe?

I hope you can advice us with this issue, we have major launch, with the project we have the issue with, coming up in short time and would need to find fix or work around to this crashing.

Hi Scourger,

Are you making any calls to FMOD\_Studio\_Bus\_UnlockChannelGroup? The callstack seems to indicate that the event’s input bus is already released before the event stops and releases, and a call to unlockChannelGroup can potentially make that happen.

Hi Tristanji,

We will check if that is the case and will return to you with an answer as soon as we can

Hello again,

we checked our code and we don´t call the FMOD\_Studio\_Bus\_UnlockChannelGroup anywhere.

Only places where we call the Bus in code are:

```
ERRCHECK (m_bus.stopAllEvents (FMOD.Studio.STOP_MODE.ALLOWFADEOUT));
ERRCHECK (m_bus.setPaused(_pause));
ERRCHECK (m_bus.setMute(_mute));

```

This is our code for handling the singleshots if you find something weird or broken from it:

```
static public void PlayOneShotWithParameter (string _event, Vector3 _position, string _parameter,float _value, float _volume=1.0f)
	{
		EventInstance eInstance;
		try
		{
			eInstance = RuntimeManager.CreateInstance(_event);
		}
		catch (Exception e)
		{
			Debug.LogError("Catched an exception when trying to play a sound event. Event is : " + _event + "Error : " + e);
			return;
		}
        SetParameter(eInstance,_parameter, _value);
        var attributes = RuntimeUtils.To3DAttributes (_position);
		ERRCHECK (eInstance.set3DAttributes (attributes));
		ERRCHECK (eInstance.setVolume (_volume));
		ERRCHECK (eInstance.start ());
		ERRCHECK (eInstance.release ());

```

I hope we can find the solution for the crash soon.

Hi,

I have gathered some more information about the crashes we are experiencing. We are using the default Unity implementation that is provided where we simply create sound instances directly from code and release them when they are not used anymore. For oneshot events we use the code provided above.

During testing we found that if we don’t use any oneshot events, the game runs pretty well and without crashes. When we use the oneshots however, the game can crash in anything between 5 to 30 minutes time. We even tried using the default oneshot functions provided in the RuntimeManager.cs but the results are the same. We even limited the amount of oneshot events played from the code to a just a few per second, but the crashes still keep coming.

We have tried increasing the real and virtual channel counts, setting dsp buffers to different values but they have no effect. Finally we also tried changing settings inside FMOD Studio to see if they have any effect. We limited ALL events to have maximum of 1 instance and their stealing set to “Virtualize”. With these settings the game crashed after an hour of playing.

There is no signs that a certain event would be the cause but rather something random happening inside the system as the log we see in Xcode is always reporting the crash happening inside “Fmod Studio update thread”.

We were forced to upgrade our implementation from 1.10.X to 2.00.09 version because of a crash issue in the old version affecting Android 9 and 10 devices reported here:  
[Android crash with FMOD 2.0.0.7](https://qa.fmod.com/t/android-crash-with-fmod-2-0-0-7/15570/11)

Immediately after we updated we started noticing the crashes we are experiencing now. The single thing we modified from our end in this migration was changing the old parameterInstance code to work with the new eventInstance setParameter functions. Since this was the only thing changed by us, we tested the oneshot events without any parameters but they still produce the crash.

Do you have any idea what could be causing this? We have provided the best logs we can. What are these pure virtual functions that seem to be called around these crashes? Do you think something might have gone wrong when we have migrated from the old version to the new one? This is rather serious as going back to the old version would bring back the other crash issue, so we are quite eager to find the cause of these problems.

And after this it will crash.

@mathew @tristanjl

Some more information about the issue, the call that seems to be causing the crash issue is: **libc++abi.dylib: Pure virtual function called!** no idea why or where this comes from but playing OneShots triggers this eventually.

Also with the latest fmod update, our Unitys seems to run out of memory after starting and stopping the game multiple times on one session and have to kill Unity to get the project running again.

Error log from the Unity memory issue:

> SystemNotInitializedException: [FMOD] Initialization failed : FMOD.Studio.System.create : ERR\_MEMORY : Not enough memory or resources.  
> FMODUnity.RuntimeManager.get\_Instance () (at Assets/Plugins/FMOD/src/Runtime/RuntimeManager.cs:114)

Here is link to screenshot of the Runtime error from Windows: [image-8 hosted at ImgBB — ImgBB](https://ibb.co/mNtbHvz)

The crash is happening on every platform that we use: Unity Win, OSX, Android and IOS, Android and IOS

We would really appreciate any help or ideas how to solve this problem!

We have decided to downgrade to version 1.10.20 because of this major crash issue and take our chances with only Android 9 and 10 crashing randomly on our project rather than all platforms crashing or freezing constantly

Hi scourger,

Thanks for all the extra information. We are still looking into the cause - we will let you know as soon as we narrow it down further.

Hi sourger,

We haven’t been able to reproduce the issue, but we have identified a potential cause. We will have a fix to address the issue we’ve discovered included our next release of FMOD which we are hoping will also address this issue.

The problem we’ve found primarily comes up when loading events that reference busses when the banks that those busses are contained in are not loaded, but it’s also possible that there are other causes we haven’t identified. We’ve only been able to reproduce a memory leak in how we were handling the error case, but potentially the crash you were encountering could arise from this issue.

Hope this information is helpful.

Hi @tristanjl,

Thank you for the update! We are really looking for possible fix in the future, until then, we just have to live with the older version of FMOD and take the hit with the crash on Android 9 and 10.

Hopefully you have the new version with possible fix on the pipeline.

Hello again @tristanjl and @mathew, sorry to bother you with this issue but do you guys have any information about the possible fix or version where the possible fix might be coming out? We would really love to update to the new version of the Fmod.

Thank you in advance!

Hi scourger,

The potential fix is in the versions just released today (2.00.10/2.01.02). If you could let us know either way if that resolves the issue, that would be really helpful.
