avaudiosession

I could make the application, to play the audio when it moves to the background, by adding the setting in info.plist file. But, when some other iOS application plays background audio, and when the current application comes to foreground, how to stop the background audio invoked by other application? Have a look at AVAudioSession class and AVAudioSession programming guide by Apple. This will hopefully steer you in the right direction. To stop background audio when your application starts set your audio session to a non-mixable category and mode then set active. If you don't configure an audio

I have some SIP application. Until I've used audio only evrything was working correctly, I was receiving AVAudioSessionInterruptionNotification when it was necessary. Problem appeared when video was used (receiving and sending camera feed). Once I use session with video, notification is never fired again, even if later audio is used only. How can I fix that? I've found similar topic , but answer is to prompt and I don't fully get it. Also I do not have "camera/capture device" and "AVCaptureSession" since audio and video streaming is provided by closed third party library, but my code have to

I am trying to play an audio through earpiece speaker and it is working fine. The same code is not working in following situation. open camera to record a video Instead of start recording, cancel it Then, trying to play an audio through earpiece not working. It is playing through main speaker Here is my code to play audio through earpiece. -(void)initialAVaudioPlayer { if (player==nil) { NSError *error = nil; AVAudioSession *session = [AVAudioSession sharedInstance]; [session setCategory:AVAudioSessionCategoryPlayAndRecord error:&error]; [session setActive: YES error:nil];

This is my first post asking a question as i never usually need help but i can't figure out if this is even possible. What i need is to switch between these two categories of avaudiosession and when the switch is made from mixing allowed to no mixing for the app take back control of the remote controls in the control center. [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback withOptions:AVAudioSessionCategoryOptionMixWithOthers error:nil] and [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback withOptions:nil error:nil] Ill try explain what is

I'm trying to solve an AVAudioSession problem since many hours ago and didn't get success!! I found lots of guys talking about problems with endInterruption but none of them talking about this error: Unable to reactivate the audio session after the interruption ended: Error Domain=NSOSStatusErrorDomain Code=560161140 "The operation couldn’t be completed. (OSStatus error 560161140.)" I tried converting this code to ASCII to check the Audio Code Results, but there is nothing related to this number. My code to init the session: - (void) setupAudioSession { mySession = [AVAudioSession

Once an audio session has been set up the following code allows bluetooth input. UInt32 allowBluetoothInput = 1; AudioSessionSetProperty (kAudioSessionProperty_OverrideCategoryEnableBluetoothInput, sizeof (allowBluetoothInput), &allowBluetoothInput); This code looks like it only allows bluetooth input however this code also routes the audio output to the bluetooth device (in the case of a bluetooth headset). I would like to route the audio output out of the line out or speaker when the input is coming from a bluetooth device. I just want to get audio input from a bluetooth device, I do not

I developed an iPhone app under iOS 5.0, and it works fine. But when it comes to iOS 4.3(Base SDK = latest iOS 5.0, compiler = Apple LLVM 3.0, Deployment Target = iOS 4.3), it crashes after launching. The output around crash point looks like: 2011-12-06 16:25:08.177 FMWei[466:c203] -[AVAudioSession setMode:error:]: unrecognized selector sent to instance 0x706a7f0 2011-12-06 16:25:08.181 FMWei[466:c203] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[AVAudioSession setMode:error:]: unrecognized selector sent to instance 0x706a7f0' It looks like that
