Sets the preferred duration, in seconds, of the IO buffer. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Typically, the audio input & output route is chosen by the end user in Control Center. I am assuming it wants a NSErrorPointer for the error but I do not know how to create one in swift. Add a & character before the variable to make it a pointer: Note: in Swift you don't have to use the method's first parameter's name. And then setCategory like this: [ [AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayAndRecord withOptions:AVAudioSessionCategoryOptionAllowBluetooth error:&error]; Once I launch the app with none exterior mics hooked up and provoke the AVAudioSession Ive the next log: That is completely tremendous. Indicates that a change occurred on the specified key. If the input port is already part of the current audio route, this will have no effect. Represents the value associated with the constant AVAudioSessionModeSpokenAudio. 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. below code for setting up the session: let audiosession = avaudiosession.sharedinstance () try audiosession.setcategory (.playandrecord, mode: .voicechat, options: [.defaulttospeaker, .mixwithothers, .allowbluetooth, .allowairplay, .allowbluetootha2dp]) try audiosession.setactive This can be a very small undertaking created to breed the difficulty. Observed changes are dispatched to the observers objectObserveValue(NSString, NSObject, NSDictionary, IntPtr)method. Is there another method I should be trying? Moreover, selecting a Bluetooth HFP output using the MPVolumeView's route picker should automatically change the input to the Bluetooth HFP input corresponding with that output. The iPhone 5 supports setting the preferred polar pattern for the "front" and "back" built-in microphones. Individual built-in microphones may be identified by a combination of a AVAudioSessionDataSourceDescription's location property (AVAudioSessionLocationUpper, AVAudioSessionLocationLower) and orientation property (AVAudioSessionOrientationTop, AVAudioSessionOrientationFront and so on). This is a very small project created to reproduce the issue. Applications may set a preferred data source by using the setPreferredDataSource:error: method of a AVAudioSessionPortDescription object. When .setPreferredInput(.) If you assume current values will always be your preferred values and for example fill our your client format using the hardware format expecting 44.1kHz when the actual sample rate is 48kHz, your application can suffer problems like audio distortion with the further possibility of other failures. As this approach is too dependent on the output string format of those processes, I didn't use it. Not the answer you're looking for? And you may control the input by assigning preferredInput property for AVAudioSession. There are several cases however where an application must first activate the audio session (after setting the appropriate category, category options and mode), in order to lean about the capabilities of the current configuration before being able to set a "preferred" value. Weakly typed; Requests a change to the Category. Any advice is highly appreciated. For example, the internal speaker on the iPhone 6S models only support a sample rate of 48kHz while previous iPhone models supported a collection of sample rates.

The typical cases are: (1) AVAudioSessionCategoryPlayAndRecord or AVAudioSessionCategoryMultiRoute this will default to false, but can be set to true. I have the following code: var iphoneInput: AVAudioSessionPortDescription = AVAudioSession.sharedInstance ().availableInputs [0] as! return} // Make the built-in microphone input the preferred input. Overriders must call base.AwakeFromNib(). This is because setting AVAudioSessionCategoryOptionDuckOthers to true will automatically also set AVAudioSessionCategoryOptionMixWithOthers to true.

Prior to calling setPreferredOutputNumberOfChannels:error:, an active audio session is required before asking for maximumOutputNumberOfChannels. All the things is completely different (and significantly better) in iOS 15. These returned values will accurately reflect what the hardware will present to the client.

Find centralized, trusted content and collaborate around the technologies you use most. Using the AVAudioSessionSetActiveOptionNotifyOthersOnDeactivation option when deactivating will reactivate other non-mixable applications. outError NSError On failure, this contains the error details. Note:Applications configured to be the main non-mixable application (e.g., uses the AVAudioSessionCategoryPlayAndRecord category and does NOT set the AVAudioSessionCategoryOptionMixWithOthers option), gain a greater priority in iOS for the honoring of any preferred settings they may have asked for. This method takes a AVAudioSessionPortDescription object. i have using twilio to perform video call across iphone devices.

For ports that support data sources (built-in microphone, some USB accessories), applications can discover what data sources are available by querying the AVAudioSessionPortDescription's dataSources property. When an application sets a preferred value, it will not take effect until the audio session has been activated. If the data source has a number of supported polar patters, you can set the preferred polar pattern by using the AVAudioSessionDataSourceDescription's setPreferredPolarPattern:error: method. Because the audio hardware of an iOS device is shared between all apps, audio settings can only be "preferred" (see SetPreferred* methods) and the application developer must account for use-cases where these preferences are overridden.
