Bonjour à tous,
J'ai branché un haut-parleur USB que je viens d'acheter.
J'ai essayé de jouer un son via un script python3 et la lib suivante.
https://pypi.org/project/audioplayer/
Après exécution du script, aucun son n'est sortie.
Qu'utilisez-vous pour commander un périphérique usb audio via un script ?
Merci d'avance.
Voici la sortie de tail -f /var/log/syslog.
