Audio J2ME Code

Question

Hello,
hi i am working on audio recorder in j2me 2.0 Ktoolbar emulator but i have been stucked up , please help me out in solving the problem,while running it wil say that it is not possible to create a player for audio/basic.i have given my code down please try to check and i am desperately need of it.
public void commandAction(Command comm, Displayable disp) {
if(comm==recordCommand) {
try {
// create the Player object using amr encoding
//p = Manager.createPlayer("capture://audio?encoding=amr");
System.out.println("hi");
p = Manager.createPlayer("capture://audio?rate=8000&bits=8&Channels=1");
//System.out.println("hi");
// p=Manager.createPlayer("capture://devmic0?encoding=pcm");
//p=Manager.createPlayer("rtp://192.168.2.2:8000/audio");
p.realize();
// get the RecordControl over this Player
RecordControl rc = (RecordControl)p.getControl("RecordControl");
// create an OutputStream which the RecordControl will use
// to write write the recorded data.
ByteArrayOutputStream output = new ByteArrayOutputStream();
rc.setRecordStream(output);
// start the recording
rc.startRecord();
p.start();
messageItem.setText("recording...");
Thread.currentThread().sleep(5000); // record for 5 seconds
messageItem.setText("done!");
rc.commit();
// save the recordedData in a byte array
recordedSoundArray = output.toByteArray();
// close the player
p.close();
} catch (IOException ioe) {
errorItem.setLabel("Error");
errorItem.setText(ioe.toString());
} catch (MediaException me) {
errorItem.setLabel("Error");
errorItem.setText(me.toString());
} catch (InterruptedException ie) {
errorItem.setLabel("Error");
errorItem.setText(ie.toString());
} else if(comm == playCommand) {
try {
ByteArrayInputStream recordedInputStream = new ByteArrayInputStream(recordedSoundArray);
Player p2 = Manager.createPlayer(recordedInputStream,"audio/basic");
p2.prefetch();
p2.start();
} catch (IOException ioe) {
errorItem.setLabel("Error");
errorItem.setText(ioe.toString());
} catch (MediaException me) {
errorItem.setLabel("Error");
errorItem.setText(me.toString());
}

catch (Exception e) {

public void recordaud()
     new dorecord().start();

     new stopplay().start();
public void commandAction(Command com, Displayable dis)
if(com == exit)
notifyDestroyed();
else if(com == stop)
init.removeCommand(stop);

else if(com == rec)
recordaud();
pls reply to me
