This is a follow-up on my previous issue #19634, where the sample project worked (when @rolfbjarne's permission string was added. But we have a similar issue in our MAUI app, where the app crashes when data is written to an AVAudioSourceNode's output buffer. From the crash log, we can't really tell, why the crash happens.

Steps to Reproduce

  1. Attach an AVAudioSourceNode to an AVAudioEngine
  2. Connect it to the mainMixerNode
  3. Write data to the AVAudioSourceNode's output buffer
using System.Runtime.InteropServices;
using AudioToolbox;
using AVFoundation;
using NAudio.Wave;

namespace Softphone
{
    public partial class Speakers
    {
        private AVAudioSourceNode _sourceNode;
        private IWaveProvider _waveProvider;
        private readonly AVAudioFormat _inputFormat = new(AVAudioCommonFormat.PCMInt16, 8000, channels: 1, interleaved: true);
        
        public void Configure(AVAudioEngine audioEngine)
        {
            _waveProvider = MediaOutput.ToWaveProvider16();
            int _bufferByteSize = _waveProvider.WaveFormat.ConvertLatencyToByteSize(20); // 20 ms of data: 320 bytes
            _sourceNode = new(_inputFormat, (ref bool isSilence, ref AudioTimeStamp timestamp, uint frameCount, ref AudioBuffers outputData) =>
            {
                try
                {
                    Console.WriteLine("MBG source node {0}, {1}, {2}, {3}", isSilence, timestamp, frameCount, outputData);

                    byte[] data = new byte[frameCount];
                    int numberOfBytes = _waveProvider.Read(data, 0, (int) frameCount);
                    IntPtr buffer = Marshal.AllocHGlobal(data.Length);
                    Marshal.Copy(data, 0, buffer, data.Length);
                    outputData.SetData(0, buffer, data.Length);
                }
                catch(Exception e)
                {
                    Console.WriteLine(e);
                }

                return 0;
            });
            audioEngine.AttachNode(_sourceNode);
            audioEngine.Connect(_sourceNode, audioEngine.MainMixerNode, _inputFormat);
        }

        public void Unconfigure(AVAudioEngine audioEngine)
        {
            audioEngine.DetachNode(_sourceNode);
        }
    }
}

Expected Behavior

Audio coming out of the speaker - and no crash.

Actual Behavior

Crash 💥

Please provide a complete test project we can use; your code snippet is incomplete (for instance, there's no code for the IWaveProvider or MediaOutput types).

[AVFoundation] Fix delegate signature for AVAudioSourceNode callbacks. (
dc4b11f 
#20357)

The signature of the callback provided when creating AVAudioSourceNode instances
was wrong, so the callback would get corrupted data, causing crashes.

Fix the callback to have the right signature (not too difficult), and also make the
existing signature work (a bit more complicated).

Note that this is the second time we've tried to fix the delegate signature for the
AVAudioSourceNode callbacks, but now with tests, so hoping there won't be a third
time.

Fixes #19868.
