    Description

      When running the demo examples/speech/hello_speak/hello_speak,
      selecting the speechd engine works, but if I select flite I get no sound and errors on the console:

      qt.speech.tts.flite: processText() begin
      QAudioOutput(pulseaudio): pa_stream_begin_write, error = Invalid argument
      QAudioOutput(pulseaudio): pa_stream_begin_write, error = Invalid argument
      QAudioOutput(pulseaudio): pa_stream_begin_write, error = Invalid argument
      QAudioOutput(pulseaudio): pa_stream_begin_write, error = Invalid argument
      QAudioOutput(pulseaudio): pa_stream_begin_write, error = Invalid argument
      QAudioOutput(pulseaudio): pa_stream_begin_write, error = Invalid argument
      ...
      qt.speech.tts.flite: "Audio error (2)"
      qt.speech.tts.flite: processText() end
      hello_speak: ../nptl/pthread_mutex_lock.c:361: __pthread_mutex_lock_full: Assertion `robust || (oldval & FUTEX_OWNER_DIED) == 0' failed.
      

      The last few lines only appeared when I closed the application.
