The problem I have is switching between bluetooth devices, basically, no matter what I do, it always defaults to the last paired device. All the code is in ViewController class. Sets the preferred duration, in seconds, of the IO buffer. func setPreferredInput(AVAudioSessionPortDescription?) Gets an array that contains descriptions of the session categories that the device can provide. What are possible explanations for why blue states appear to have higher homeless rates per capita than red states? Therefore, asking for the current hardware buffer duration or sample rate before AVAudioSession activation could return incorrect values. Use OutputNumberOfChannels instead. Overriders must call base.AwakeFromNib(). ). Why does secondary surveillance radar use a different antenna design than primary radar? And you might management the enter by assigning preferredInput property for AVAudioSession. How dry does a rock/metal vocal have to be during recording? The following is based on paring the devices in the following order, In this setup, the BeatsStudio Wireless always wins. TL;DR: Starting from iOS 16 I face a weird behaviour of the AVAudioSession that breaks my app. AVAudioSession.setPreferredInput (Showing top 2 results out of 315) origin: ibinti/bugvm /** * @since Available in iOS 7.0 and later.

That is an smallest instance undertaking to breed the difficulty. See AVAudioSession.h. input of the AVAudioSession route is MicrophoneWired Everything is different (and much better) in iOS 15. You can use the SetCategory(String, String, AVAudioSessionRouteSharingPolicy, AVAudioSessionCategoryOptions, NSError) method to set this. 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. Whether another application is currently playing back audio. Registers an object for being observed externally using an arbitrary method. Returns the current Objective-C retain count for the object. This is a very small project created to reproduce the issue. Returns Boolean true if the request was successful, otherwise the outError parameter contains an instance of NSError describing the problem. In other words, both the input and output should always end up on the same Bluetooth HFP device chosen for either input/output even though only the input or output was set individually. Is there another method I should be trying? Represents the value associated with the constant AVAudioSessionModeSpokenAudio. Sets the values of this NSObject to those in the specified dictionary. Observed changes are dispatched to the observers objectObserveValue(NSString, NSObject, NSDictionary, IntPtr)method. By default TwilioVideo will manage the application's AVAudioSession and configure it for video conferencing use cases. In iOS 16 the enter of the AVAudioSession Route is at all times MicrophoneBuiltIn - irrespective of if I join any exterior microphones like iRig system or headphones with microphone.

A: While it is safe to set the AVAudioSession audio category (setCategory:error:) or notification listeners like AVAudioSessionRouteChangeNotification for example, regardless of activation state, it is generally better to make preference requests such as preferred hardware buffer duration (setPreferredIOBufferDuration:error:) or preferred hardware sample rate (setPreferredSampleRate:error:) when the AVAudioSession is NOT active. Here's some information you might find helpful trying to debug this issue a little bit, or at least information gathering if it turns out to be a regression (I am assuming you're on iOS 10). Switching between the built in ear speaker, speaker and wired headset works perfectly fine (through a combination of outError NSError On failure, this contains the error details. Please let me know if there may be any method to make the behaviour of iOS 16 the identical its on iOS 15 and beneath. This can be a very small undertaking created to breed the difficulty.

Listing 1 in Q&A1799 has some input selection demo code. Then I tried to change preferredInput of the AVAudioSession first to MicrophoneWired, then to MicrophoneBuiltIn and then to MicrophoneWired again: No matter what is preferredInput the input device of AudioSession route is MicrophoneBuiltIn. Therefore both the input and output will always end up on the Bluetooth HFP device even though only the input or output was set individually. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Display screen Printing Stretchable Digital Units, This search and rescue robotic creates 3D maps of catastrophe areas, android Does anyone know why I am getting this error and the right way to repair it? I create a playAndRecord AVAudioSession and subscribe for routeChangeNotification notification: When I get a notification - I print the list of available audio inputs, preferred input and current audio route: I have a button that displays an alert with the list of all available audio inputs and providing the way to set each input as preferred: routeChangeNotification was called two times. 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. Any recommendation is extremely appreciated. is determined eithe, General file manipulation utilities. Constructor to call on derived classes to skip initialization and merely allocate the object. The order AVAudioSession. I then use session.setPrefferedInput to switch the input, when using "BeatsStudio Wireless", it will generate the following: When I try changing to the mini503 it outputs: Which clearly shows that the route has not changed.

In Listing 1 the AVAudioSession has been activated prior to asking for the current hardware sample rate and current hardware buffer duration. The duration of the current buffer, in seconds. Instead, I chose the PulseAudio server to fetch available devices on my system. This is an smallest example project to reproduce the issue. The preferred method for overriding to the speaker instead of the receiver for speakerphone functionality is through the use of MPVolumeView. Applications may set the audio session option AVAudioSessionCategoryOptionDefaultToSpeaker or use the AVAudioSessionPortOverrideSpeaker override for speakerphone functionality. Handle used to represent the methods in the base class for this NSObject. This is because setting AVAudioSessionCategoryOptionDuckOthers to true will automatically also set AVAudioSessionCategoryOptionMixWithOthers to true. i have using twilio to perform video call across iphone devices.
