I think the problem is simple try to implement you info.plist like my screen:

And if you want you can add the function on AppDelegate.m under the didFinishLaunchingWithOptions to enable Bluetooth, AirPlay WiFi and more, this is only a example code, but i think can help you.

NSError *sessionError = nil;
[[AVAudioSession sharedInstance] setDelegate:self];
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayAndRecord error:&sessionError];
[[AVAudioSession sharedInstance] setActive:YES error:nil];

UInt32 sessionCategory = kAudioSessionCategory_MediaPlayback;
AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(sessionCategory), &sessionCategory);

UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;
AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute,sizeof (audioRouteOverride),&audioRouteOverride);

[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];

Hope this can help you.
