Hey,
Using FMOD Studio 2.01.07 for Unity 2019.4.28f1, and I’m getting the following error on every frame in Development build for Windows:
[FMOD] AsyncManager::asyncThreadLoop : System::update returned error 2.
UnityEngine.DebugLogHandler:LogFormat(LogType, Object, String, Object[])
UnityEngine.Logger:Log(LogType, Object)
UnityEngine.Debug:LogError(Object)
FMODUnity.RuntimeManager:DEBUG_CALLBACK(DEBUG_FLAGS, IntPtr, Int32, IntPtr, IntPtr)
It only just started appearing after the integration has worked fine for nearly two years. After updating to 2.01.07 I have seen some problems in the Unity Editor such as intermittent crashes and audio sticking around after exiting playmode, but builds have always worked fine until now.
What can I do?
Managed to halfway work around this problem by setting all audio content to STREAM. I had previously avoided this because it causes different tracks to desynchronize, and I don’t consider it to be a solution just an indicator of what might be wrong.
It didn’t really solve the problem entirely either, since this problem popped up in its place: DllNotFoundException: Unable to load DLL ‘fmodstudio’: The specified module could not be found
The game only works in development builds now.
Looks like I solved this by increasing the number of virtual and real audio channels!
Glad to hear you got that working! FMOD_RESULT of 2 evaluates to FMOD_ERR_CHANNEL_ALLOC so increasing the number of channels makes sense- strange the error only ocurred post 2.01.07 though. If you can please share any logs next time you get a crash that would be appreciated.
Thank you for sharing your solution!
