[Mac] Audio recording on .NET8

[mcocaroUX]

I'm currently working on a project targeting Mac, we recently migrated to .NET 8 and our audio recording functionality broke. While the audio file is created with the correct duration, it produces no sound upon playback.

My first assumption was that AVAudioSession wasn't selecting the correct device, but is not the case.

We're using AVAudioRecorder for audio recording. To troubleshoot, I also experimented with AVCapture and AVAudioEngine, but the outcome remained the same

Here is a snip of our code:

AVAudioRecorder _audioRecorder;
NSError _error;

var session = AVAudioSession.SharedInstance();

if(session is not null)
{
    session.SetActive(true);

    session.SetCategory(AVAudioSessionCategory.PlayAndRecord);
}

var settings = new AudioSettings
{
    Format = AudioFormatType.MPEG4AAC,
    SampleRate = 44100.0f,
    NumberChannels = 1,
    AudioQuality = AVAudioQuality.High
};

_audioRecorder = AVAudioRecorder.Create(NSUrl.FromFilename(_filePath), settings, out error);

_audioRecorder.Record();

Any ideas?

Thanks
