im using
public static void playAudioFromByteArray(byte[] audio,
AudioFormat format) throws Exception {
if(format==null)
format=new AudioFormat(44000f, 8, 1, true, true);
final AudioFormat _format = format;
InputStream input = new ByteArrayInputStream(audio);
final AudioInputStream ais = new AudioInputStream(input, format,
audio.length / format.getFrameSize());
DataLine.Info info = new DataLine.Info(SourceDataLine.class, format);
final SourceDataLine line = (SourceDataLine) AudioSystem.getLine(info);
line.open(format);
line.start();
if(playThread!=null){
//playThread.stop();
}
runner = new Runnable() {
int bufferSize = (int) _format.getSampleRate()
* _format.getFrameSize();
byte buffer[] = new byte[bufferSize];
private boolean _playing;
public void run() {
try {
int count;
_playing = true;
while ((count = ais.read(buffer, 0, buffer.length)) != -1) {
//progress++;
if (count > 0) {
line.write(buffer, 0, count);
}
if (! _playing)
break;
}
_playing = false;
line.drain();
line.close();
} catch (Exception e) {
e.printStackTrace();
}
}
};
playThread = new Thread(runner);
playThread.start();
}
to play sounds recorded from the mic
but on some pcs i get
EDIT: i tryied with 32000 also
javax.sound.sampled.LineUnavailableException: line with format PCM_SIGNED 44000.0 Hz, 8 bit, mono, 1 bytes/frame, not supported.

Is there some way to use a poor quality audioformat and be sure that it will work on any machine? or to detect what audioformats are avaliable?
EDIT2:
with Greg code i get
