@Varun Bhatia,
yes i can
my simple recording test app works great on the desktop and on Android.
on the other hand, on ios (iPhone 3gs, latest os) i sometimes hear nothing on playback, sometimes just the end of the recording, sometimes the playback is stuttering.
thanx,

i am using flash pro cs5.5 overlayed with the AIR 3 sdk.
the FLA contains two movieclips on stage named "recorder" and "player". they act as buttons. all the code is in the document class:
package  {
          import flash.display.Sprite;
          import flash.media.Microphone;
          import flash.media.Sound;
          import flash.media.SoundChannel;
          import flash.events.MouseEvent;
          import flash.events.SampleDataEvent;
          import flash.utils.ByteArray;
          import flash.events.Event;
          import flash.media.SoundMixer;
          import flash.media.AudioPlaybackMode;
          public class RecTest extends Sprite {
                    var mic:Microphone;
                    var s:Sound;
                    var sc:SoundChannel;
                    var nowRecording:Boolean = false;
                    var nowPlaying:Boolean = false;
                    var recordedBytes:ByteArray;
                    public function RecTest() {
                              SoundMixer.audioPlaybackMode = AudioPlaybackMode.MEDIA;
                              mic = Microphone.getMicrophone();
                              mic.rate = 44;
                              mic.gain = 70;
                              mic.setSilenceLevel(0);
                              s = new Sound();
                              recordedBytes = new ByteArray();
                               recorder.addEventListener(MouseEvent.CLICK, record);
                               player.addEventListener(MouseEvent.CLICK, playBack);
                    function record(e:MouseEvent) {
                              if (!nowRecording) {
                                        trace("recording");
                                        recordedBytes.clear();
                                        mic.addEventListener(SampleDataEvent.SAMPLE_DATA, getMicAudio);
                                        nowRecording = true;
                              } else {
                                        trace("recording stopped");
                                        mic.removeEventListener(SampleDataEvent.SAMPLE_DATA, getMicAudio);
                                        nowRecording = false;
                    function getMicAudio(e:SampleDataEvent) {
                              recordedBytes.writeBytes(e.data);
                    function playBack(e:MouseEvent) {
                              if (!nowPlaying) {
                                        trace("playing");
                                        recordedBytes.position = 0;
                                        s.addEventListener(SampleDataEvent.SAMPLE_DATA, playAudio);
                                        sc = s.play();
                                        sc.addEventListener(Event.SOUND_COMPLETE, stopPlayback, false, 0, true);
                                        nowPlaying = true;
                              } else {
                                        sc.stop();
                                        stopPlayback();
                    function stopPlayback(e:Event=null) {
                              trace("playing stopped");
                              s.removeEventListener(SampleDataEvent.SAMPLE_DATA, playAudio);
                              nowPlaying = false;
                    function playAudio(e:SampleDataEvent) {
                              for (var i:int = 0; i < 8092 && recordedBytes.bytesAvailable > 0; i++) {
                                        var sample:Number = recordedBytes.readFloat();
                                        e.data.writeFloat(sample);
                                        e.data.writeFloat(sample);
