I am trying to reproduce the issue, and I notice it hangs with sine.mp3
but not with sine.wav (my build did not have a MP3 encoder), and I find
it very strange, even with the current code. Please let me look into it
closer; but if you have an idea about why MP3 input behaves different
than WAV please let me know.
