how does 'Hi Res Output' API release/re-acquire driver once a notification is triggered (i.e. Waze/Google nav)

@maxmp

please address how this works, given the experimental API is not part of the Android kernal (right? such as OpenSL ES is).  is  the app truly regaining control or does it just default to OpenSL ES when a notification is triggered?
