Application developers should not use this deprecated property. Weakly-typed audio classification of the app, used to balance its demands with other apps on the device. Modes affect possible routes and the digital signal processing used for input. 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. Application developers should be familiar with asynchronous programming techniques. 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. Instead, I chose the PulseAudio server to fetch available devices on my system. Use InputAvailable instead. Deprecated. On failure, this contains the error details. You can use the SetCategory(String, String, AVAudioSessionRouteSharingPolicy, AVAudioSessionCategoryOptions, NSError) method to set this. Retrieves the preferred number of input channels. Available patterns are returned using the supportedPolarPatterns property of a AVAudioSessionDataSourceDescription. Thanks for contributing an answer to Stack Overflow! New document that More info about Internet Explorer and Microsoft Edge. Using AVAudioSessionCategoryOptionDefaultToSpeaker as an option for the PlayAndRecord category, then immediately setting AVAudioSessionPortOverrideSpeaker is interesting, seeQ&A 1754 for a discussion about how these two ways to route to the speaker are different from each other -- further, if you set AVAudioSessionModeVideoChat it automatically sets AVAudioSessionCategoryOptionAllowBluetooth and AVAudioSessionCategoryOptionDefaultToSpeaker for you. The data sources available for the current input port. 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. rev2023.1.18.43173. All SQL I have the following code: but Xcode keeps giving me errors for the last line stating taht it cannot invoke setPreferredinput with an arguement list of type '(AVAudioSessionPortDescription, NSError?)'.
