Audio no longer captured on iOS

[tekmun]

Hi,

With iOS 12.2, audio is no longer captured. Same code but the AudioInputReceived event is not called.

Is anything logged when you begin recording? Wondering there's an exception happening that's preventing things from getting started.

The issue is solved by adding the suggested ConfigureAVAudioSession in iOS AppDelegate.cs.

I've noticed a simulair issue for iOS. After starting recording the recorder never sets recording to true. I use the plugin.MediaManager also. No issues with android though.

' the suggested ConfigureAVAudioSession in iOS AppDelegate.cs.' does not seem to work with iOS 13.1.2 I am getting the error 'audioQueue.Start() returned non-OK status: GeneralParamError ' again. I've tried adding:

 var audioSession = AVAudioSession.SharedInstance();

            // If AVAudioSessionCategoryOptions.MixWithOthers option is cleared, activating your session interrupts other audio sessions. If this option is set, your app's audio is mixed with audio playing in background apps (such as the Music app).
            var audioError = audioSession.SetCategory(AVAudioSessionCategory.PlayAndRecord, AVAudioSessionCategoryOptions.MixWithOthers);

and withoud the AVAudioSessionCategoryOptions.

Edit:

Some additional info: iPhone11 version 13.1.2, iOS,

audioQueue.Start() returned non-OK status: GeneralParamError

Implemented a DependencyService to change the category back and forth. That worked like a charm. I red that this was not necessarily for version 1.0.1 and beyond. But it seems that this is necessarily (again?)

(adding this in the AppDelegate.cs is not sufficient)

I also had problems with the default setup of the plugin on iOS 13.1.2 and made a DependencyService to workaround it. That worked, but after further reading the documentation and the source code, I also found that just specifying the category for BOTH play and record in the AppDelegate.cs worked equally well, i.e.:

// Make audio behave sensible to our needs for both play and record AudioPlayer.RequestAVAudioSessionCategory(AVAudioSessionCategory.Playback); AudioRecorderService.RequestAVAudioSessionCategory(AVAudioSessionCategory.Record);

This also solves another issue: by default, it will playback sound using the small upper speaker for telephone conversations, making it almost inaudible unless you put the phone up to your ear. But explicitly specifying PlayBack automatically switches it to the larger speakers at the bottom, unless you attach headphones, which is precisely what you want.

So maybe the default settings should be like this? Or at least update the iOS section of the ReadMe.md file to reflect that this is a necessary configuration for most usages.

I've used BOTH too. But the mediamanager plugin resets it. So you will still need to set it back and forth.
