avaudiosession

I working on a little app where i want the phone to play a sound file on an event from my location controller. The problem is when the App is in Background mode the AVAudioPlayer not start the Audio file but the code is scheduled, getting NSLog output. Another thing is it works in the simulator but not on the phone. Whys not? This is my code to play the file: - (void)tryPlayTaleSound:(NSString*)fileName { NSString *backgroundMusicPath = [[NSBundle mainBundle] pathForResource:fileName ofType:@"mp3"]; NSURL *backgroundMusicURL = [NSURL fileURLWithPath:backgroundMusicPath]; NSError *error;

I can not seem to override the AVAudioSession category or port when audio is being played from a WKWebView. The same code works perfectly when using a normal UIWebView. AVAudioSession *session = [AVAudioSession sharedInstance]; [session setCategory:AVAudioSessionCategoryPlayAndRecord error:&err]; I've also tried activating the sharedInstance like this, but it did not help: [session setActive: YES error: nil]; The above code has no effect on audio coming from a WKWebView. I did find some reports on Twitter that iOS 8.1 is mixing WKWebView audio with background app audio, but I couldn't find the

I've been playing with phone calls while (SpriteKit)game running in order to test interruptions. I am using example from ObjectAL documentation called : "Using the OpenAL Objects and OALAudioTrack" . So, I let the library to handle this automatically... [OALAudioSession sharedInstance ]. handleInterruptions = YES And it works but partially.

(OSStatus

Okay, I have my AVAudioSession defined with the following (yes, mix of the c and obj-c calls) Also note that the app has background mode audio, because if recording it must continue to do so while the app is in the background: [(AVAudioSession *)[AVAudioSession sharedInstance] setDelegate: self]; // Allow the app sound to continue to play when the screen is locked. [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayAndRecord error:nil]; //Turn off automatic gain on the microphone [[AVAudioSession sharedInstance] setMode:AVAudioSessionModeMeasurement error:nil]; //Turn on

There are three different Bluetooth related audio port types documented in Apple's AVAudioSessionPortDescription reference. But Apple doesn't explain much about these three types. Can somebody help explain more? AVAudioSessionPortBluetoothHFP | Input and Output This is used when connected to a bluetooth devices through Hands-Free profile, like cars or earpieces. It can be accessed by setting your audio session category to AVAudioSessionCategoryPlayAndRecord and category option AVAudioSessionCategoryOptionAllowbluetooth . AVAudioSessionPortBluetoothA2DP | Output only This is mainly used for

I'm very new to Objective-C, and am trying to update some code that's about 3 years old to work with iOS 7. There are two or two instances of AudioSessionSetProperty and AudioSessionInitialize appearing in the code: 1: - (void)applicationDidFinishLaunching:(UIApplication *)application { AudioSessionInitialize(NULL,NULL,NULL,NULL); [[SCListener sharedListener] listen]; timer = [NSTimer scheduledTimerWithTimeInterval: 0.5 target: self selector: @selector(tick:) userInfo:nil repeats: YES]; // Override point for customization after app launch [window addSubview:viewController.view]; [window
