Currently, I am trying to figure out how to play audio within a Digital Ocean Dockerfile container. The full writeup is here: https://stackoverflow.com/questions/75035203/pygame-midi-playback-in-paas-from-dockerfile
It is a Python Flask App; currently stuck at this error: pygame.error: ALSA: Couldn’t open audio device: No such file or directory
