when use unity Microphone.Start to record audio and pause fmod then resume after stop record.  
the problem is: the bgm sound will appear after a few seconds (7second or more). on ios phone.  
why there is a delay?

begin record:  
OnApplicationPause(true);  
Microphone.Start(xxx)

end record:  
Microphone.Stop()  
OnApplicationPause(false);

OnApplicationPause will be calling `coreSystem.mixerSuspend/Resume` which will stop all sounds running in FMOD, although I’m not sure why there would be a delay in resuming.

If you don’t want the sounds to actually pause, you could also use `RuntimeManager.MuteAllEvents`.

It is my fault, i make a delay manually in the code, so the sound can not resumed immediately. thank u very much.
