I resolve it!Uhhhuuu....)

here is my c# code

correct settings

await SendCommand("SET auth t=kiwi p= ");

await SendCommand("SET AR OK in=12000 out=12000");

await SendCommand("SET squelch=0 max=0");

await SendCommand("SET genattn=0");

await SendCommand("SET gen=0 mix=-1");

await SendCommand("SET ident_user=kiwibob");

await SendCommand("SET mod=usb low_cut=0 high_cut=6000 freq=10100.000");

await SendCommand("SET agc=1 hang=0 thresh=-110 slope=6 decay=1000 manGain=50");

await SendCommand("SET compression=0");

await SendCommand("SET keepalive");

code for process byte array, received from KiwiSDR

 var buffer = new byte[4096];

 while (true)

 {

   var result = await socket.ReceiveAsync(new ArraySegment<byte>(buffer), CancellationToken.None);

   if (result.MessageType == WebSocketMessageType.Close)

   {

     await socket.CloseAsync(WebSocketCloseStatus.NormalClosure, "", CancellationToken.None);

     break;

   }

   if (result.MessageType == WebSocketMessageType.Binary)

   {

     if (Encoding.ASCII.GetString(buffer, 0, 3) == "SND")

     {

       int audioLength = result.Count - 16;

       if (audioLength <= 0) return;

       byte[] audioBytes = new byte[audioLength];

       Array.Copy(buffer, 16, audioBytes, 0, audioLength);

       // Convert from Big Endian to Little Endian

       for (int i = 0; i < audioBytes.Length; i += 2)

       {

         byte tmp = audioBytes[i];

         audioBytes[i] = audioBytes[i + 1];

         audioBytes[i + 1] = tmp;

       }

       audioPlayer.provider.AddSamples(audioBytes, 0, audioBytes.Length);

     }

   }

Settings for WaveOut

class KiwiAudioPlayer

{

  public BufferedWaveProvider provider;

  private WaveOutEvent waveOut;

  public KiwiAudioPlayer()

  {

    var waveFormat = new WaveFormat(12000,16, 1); // 12kHz, 16-bit, Mono

    provider = new BufferedWaveProvider(waveFormat)

    {    

      DiscardOnBufferOverflow = true

    };

    waveOut = new WaveOutEvent();

    waveOut.Init(provider);

    waveOut.Play();

  }

  public void AddAudioBytes(byte[] audioBytes)

  {

    provider.AddSamples(audioBytes, 0, audioBytes.Length);

  }

  public void Stop()

  {

    waveOut?.Stop();

    waveOut?.Dispose();

  }

}

Thank U!
