I have converted a .wav file to mts, but cant get the sound to play. The sound is just a recording of a drawer opening, nothing fancy.

I tried testing it using the tester (I had to change the opacity of the play button in the tester mtx to get it to show in the html, it was totally transparent) but still no sound. I even tried loading the sample mts file 'nine' that came with the zip, but no sound from that either. Is there something I am doing wrong?
