Below is the output. Note, that audacious 2.x was not only skipping a little bit. In fact, the clock that was showing the time of audio played was running twice as fast or even 4 times as fast. The sound was played at the right samplerate but in fast it seems, that much of the audio data was skipped and I only heard a series of short fragments of what should have been the song I'm listening to.
