AudioTrack does not have a WriteAsync. For dot42, use this line:
await Task.Factory.StartNew( () => audioTrack.Write(buffer, 0, buffer.Length) );
I assume this works for Xamarin as well.

I've tried to use Xamarin example of audio record/play using the follow code: Example_WorkingWithAudio
At the following Task
i have async
error:
protected async Task PlayAudioTrackAsync ()
{
audioTrack = new AudioTrack (
// Stream type
Android.Media.Stream.Music,
// Frequency
11025,
// Mono or stereo
ChannelConfiguration.Mono,
// Audio encoding
Android.Media.Encoding.Pcm16bit,
// Length of the audio clip.
buffer.Length,
// Mode. Stream or static.
AudioTrackMode.Stream);
audioTrack.Play ();
await audioTrack.WriteAsync (buffer, 0, buffer.Length);
}
Changed for dot42:
protected async Task PlayAudioTrackAsync()
{
audioTrack = new AudioTrack (AudioManager.STREAM_MUSIC,11025,
AudioFormat.CHANNEL_OUT_MONO,
AudioFormat.ENCODING_PCM_16BIT,
buffer.Length,
AudioTrack.MODE_STREAM
);
audioTrack.Play ();
await audioTrack.WriteAsync(buffer, 0, buffer.Length);
}
How do i change "audioTrack.WriteAsync" ? I've compiler error on this line.

Apart from that answer i also used audioTrack.WriteAsync() method to play audio async. I think need not create an async method.Here is what playing audio asynchronously.
public void audioTrackPlay(byte[] audioBuffer){try {
audioTrack.Play();
// audioTrack.Write(audioBuffer, 0, audioBuffer.Length);
audioTrack.WriteAsync(audioBuffer, 0, audioBuffer.Length);
Toast.MakeText(this,"Server Started",ToastLength.Short).Show();
} catch (Exception e) { } }
