Play audio Stream with AudioTrack in Marshmallow

When I try to execute this part of code in android Lollipop version. Everything is ok. But in Marshmallow version is not working : 

public static void play() {

    InputStream generetedStream =  ...;

    int minBufferSize = AudioTrack.getMinBufferSize(16000, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT);
    AudioTrack trackw = new AudioTrack(AudioManager.STREAM_MUSIC, 16000, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, minBufferSize, AudioTrack.MODE_STREAM);


    int bufferSize = 1024;
    byte[] lin = new byte[bufferSize];
    trackw.play();

    int i = 0;
    if (generetedStream != null) {
        while (generetedStream != null && (i = generetedStream.read(lin, 0, bufferSize)) > -1) {
            trackw.write(lin, 0, lin.length);
        }
    }

}

Added permissions : 

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />

is there any changing AudioTrack in Marshmallow version ???

Try to set runtime permission for version 6.0.

if(Build.VERSION.SDK_INT>=23){
    int permissionCheck = ContextCompat.checkSelfPermission(MainActivity.this,
            Manifest.permission.READ_PHONE_STATE);
    if (permissionCheck != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(MainActivity.this,
                new String[]{Manifest.permission.READ_PHONE_STATE},
                MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);
    } else {
        // your code
    }
}else{
    // your code
}

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_READ_PHONE_STATE: {
            if (grantResults.length > 0
                    && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // permission granted -code

            } else {

                // permission not granted - code
            }
        }
    }
}

You can add other permission whichever required...
