I have a very simple setup involving AVAudioEngine, and a player node, AVAudioPlayerNode.
The player node is attached to the audio engine, then connected to the engine's main mixer node.
Then, to start outputing some sound, I start the engine, and finally play the node :
NSError* err = nil;
BOOL started = [_audioEngine startAndReturnError:&err];
if(started) {
[_playerNode play];
} else {
// handle error
}It happens sometimes, the app crashes (on the call to the play function) because, as the system says : "player started when engine not running".
I can't understand how this can happen, at least in the code above.
No error is returned in `err`.
Does somebody knows what happen or faced such a situation ?
