Unity hang after exiting play mode

0 votes

Hi,

I was attempting to integrate wwise into a Unity project using Unity 2019.3.  I'm using Wwise 2019.2.0 build 7216.  Everything was going smoothly until I started testing in levels.  There are some levels where after testing in the editor, Wwise hangs and completely locks up Unity.  Looking at the call stack, it's here:

AkSoundEngine:ClearBanks ()+0x1 at D:\projects\XXX\Assets\Wwise\Deployment\API\Generated\Windows\AkSoundEngine_Windows.cs:[530:41-530:99]

AKRESULT AkSoundEngine:ClearBanks ()+0x1 at D:\projects\xxx\Assets\Wwise\Deployment\API\Generated\Windows\AkSoundEngine_Windows.cs:[530:41-530:99]

Void AkWwiseInitializationSettings:TerminateSoundEngine ()+0x18 at D:\projects\xxx\Assets\Wwise\Deployment\API\Handwritten\Common\AkWwiseInitializationSettings.cs:[385:3-385:30]

Void AkSoundEngineController:Terminate ()+0x17 at D:\projects\xxx\Assets\Wwise\Deployment\Components\AkSoundEngineController.cs:[148:3-148:56]

Void AkInitializer:OnApplicationQuit ()+0x15 at D:\projects\xxx\Assets\Wwise\Deployment\Components\AkInitializer.cs:[79:4-79:49]

This is happening 100% of the time on my level, both on OSX and in Windows.  I took a look at the process threads; it looks like the main unity thread may be waiting on thread Thread_193361 which is waiting for some other thread..

I'm not sure what to do from here.  Any help?

thanks,
