SimpleaudioError: Error opening PCM device

1.1k Views Asked by At

I want to use python to play certain muscial notes depending on some results I obteined erlier in my code. I'm using pydub and I downloaded some .wav sounds in my google colab document. However, I have an error that I can't quit figure out. Here's my code

from pydub import AudioSegment
from pydub.playback import play

note_do = AudioSegment.from_wav(r"/95328__ramas26__c.wav")
note_re = AudioSegment.from_wav(r"/95329__ramas26__d.wav")
note_mi = AudioSegment.from_wav(r"/95330__ramas26__e.wav")
note_fa = AudioSegment.from_wav(r"/95331__ramas26__f.wav")
note_sol = AudioSegment.from_wav(r"/95332__ramas26__g.wav")
note_la = AudioSegment.from_wav(r"/68437__pinkyfinger__piano-a.wav")
note_si = AudioSegment.from_wav(r"/95327__ramas26__b.wav")

for i in range(len(notes_fin)):
  if notes_fin[i]==0:
    play(note_do)
  if notes_fin[i]==1:
    play(note_re)
  if notes_fin[i]==2:
    play(note_mi)
  if notes_fin[i]==3:
    play(note_fa)
  if notes_fin[i]==4:
    play(note_sol)
  if notes_fin[i]==5:
    play(note_la)
  if notes_fin[i]==6:
    play(note_si)

The if statement are based on things I had earlyer in the code. Here's the error I have :

     16     play(note_re)
