If `sound->getOpenState` equals `FMOD_OPENSTATE_CONNECTING`, then `sound->release()` sound will freeze the main thread, even if the release operation is in the sub thread.

I run code on the ios system.  
FMOD Studio API Version : `iOS 2.00.07`

Is there a solution?

Are you able to reproduce this in our netstream example, in the API Core examples?
