Playing wav files with python simpleaudio produces: SimpleaudioError: Unable to start queue. -- CODE: -66681

import simpleaudio as sa

wave_obj = sa.WaveObject.from_wave_file('path to wav file/test.wav')
play_obj = wave_obj.play()
play_obj.wait_done()  # Wait until sound has finished playing

The code was working until I installed a few packages (firebase, Crypto, python_jwt, cryptodome, pycrypto). Now it produces:

SimpleaudioError                          Traceback (most recent call last)

      3 wave_obj = sa.WaveObject.from_wave_file('/Users/mohamed/Files/IBM Watson TTS/Segments/output.wav')
----> 4 play_obj = wave_obj.play()
      5 play_obj.wait_done()  # Wait until sound has finished playing

Solution

  • Restarting the computer fixed it.
