Getting the same error. I am receiving audio from WATSON Cloud service

  textToSpeech.synthesize(synthesizeParams)
  .then(audio => {
    audio.pipe(speaker);
  })
  .catch(err => {
    console.log('err:', err);
  });

But it breaks after I receive the second audio.

My solution for this was creating a speaker instance per call

  textToSpeech.synthesize(synthesizeParams)
  .then(audio => {
    const speaker = new Speaker({
      channels: 1,          // 2 channels
      sampleRate: 22050     // 44,100 Hz sample rate
    })
    audio.pipe(speaker);
  })
  .catch(err => {
    console.log('err:', err);
  });

very nice @trafalmejo that helped me as well

This happens when you are writing to the stream after you have ended.

The correct solution is to either create a new Speaker for each stream you want to pipe, or to pipe with { end: false }
