reuse sdk.AudioInputStream.createPushStream() with same data gives another recognizer.recognizeOnceAsync result

See original GitHub issue

I used the provided node.js sample to experiment. When I want to reuse/loop my code, the recognize results are wrong. The first loop the result is ok, but the next loops the results are all wrong. I problem seems to be the way I reuse/rebuild pushStream variable. I expect 5 times the same results, when I read 5 times the same WAV file and do 5 times the recognition.

`function loop() { // create the push stream we need for the speech sdk. var pushStream = undefined; pushStream = sdk.AudioInputStream.createPushStream();

// open the file and push it to the push stream. fs.createReadStream(filename).on(‘data’, function (arrayBuffer) { pushStream.write(arrayBuffer.buffer); }).on(‘end’, function () { pushStream.close(); analyse(pushStream); // Rest of sample code where recognition is done. When done, loop() is called again. }); }`

Expected behavior I try to reset all variables, so I expect the recognition result is always the same.
