I am also having the same problem with version 2.7. Here is the output, this is from the point I first load the code, I then hit my button the first time and get nothing, hit it a second time and it plays the sound, but in all cases there seems to be errors and more going on than should be. like i appears the success fires more than the one success.. Out put and my code below...
