It doesn't happen when .setPreferredInput() is called before unplugging the EarPods. Instead, they should use ObserveInterruption(NSObject, EventHandler
In most cases where setting a preferred value causes some sort of audio system reconfiguration with an active audio session, audio data I/O will be stopped and then restarted. How strong is a strong tie splice to weight placed in it from above? Note You can activate the audio session at any time after setting its category, but it's generally preferable to defer this call until your app begins audio playback. By default TwilioVideo will manage the application's AVAudioSession and configure it for video conferencing use cases. Why is Bb8 better than Bc7 in this position? The number of channels for the current input route.

I am assuming it wants a NSErrorPointer for the error but I do not know how to create one in swift. Registers an object for being observed externally (using string keyPath). Important:Keep in mind the side effects of an audio session going inactive: If AVAudioSessionCategoryOptionDuckOthers has been set, going inactive will end ducking.

Therefore, if an application plans to set multiple preferred values, it is generally advisable to deactivate the session first, set the preferences, reactivate the session and then check the actual values.
Invokes asynchrously the specified code on the main UI thread. For instance, the iPhone 4 and iPhone 4S have two microphones:
Listing 1 // Configure the audio session for playback and recording NSError *audioSessionError = nil; AVAudioSession *session = [AVAudioSession sharedInstance]; Performs a copy of the underlying Objective-C object. Can the use of flaps reduce the steady-state turn radius at a given airspeed and angle of bank? Did an AI-enabled drone attack the human operator in a simulation environment?
Deprecated. As previously stated, these values may be different then what was asked for using the "Preferred" APIs. Developers can also manually select microphones and even select a preferred microphone polar pattern if the hardware supports it. We can use the temporary directory (were going to record a 4 sec audio file which is ridiculous).

avaudiosession setpreferredinput. discover available data sources by querying the port descriptions Because of the characteristics of Simulator, you may want to conditionalize your code to allow partial testing in Simulator.
Your input helps improve our developer documentation. Instead use M:AVFoundation.AVAudioSession.SetPreferredSampleRate(Double, out NSError). If not overridden, raises an NSUndefinedKeyException.
The current number of channels in the output route. These preferred values are simply hints to the operating system, the actual buffer duration or sample rate may be different once the AVAudioSession has been activated.
The default value is unset. Changes to preferred values take effect after the audio session is activated, and you can verify the changes at that time. You should also control the Mode (using SetMode(NSString, NSError) to describe how your application will use audio. Sets the values of this NSObject to those in the specified dictionary. VideoEncodingMode represents the modes of behavior of the videoEncodingMode property in ConnectOptions. That is an smallest instance venture to breed the difficulty.
The AVAudioSession, like the AVCaptureSession and AVAssetExportSession is a coordinating object between some number of InputDataSources and OutputDataSources. Observed changes are dispatched to the observers objectObserveValue(NSString, NSObject, NSDictionary, IntPtr)method. Apps may set a preferred data source by using the setPreferredDataSource:error: method of an AVAudioSessionPortDescription object. For example, the input and output audio routes can be overwritten by altering the AVAudioSession configuration in the block that you provide to DefaultAudioDevice.
