[Son] Problèmes de micro
Publié : sam. 20 juin 2026, 14:40
Bonjour,
Je ne parviens pas à faire fonctionner mon micro sous Endeavour/KDE. Que ce soit le micro interne du PC ou un casque branché sur la prise dédiée. Pourriez-vous m'aider à identifier et résoudre le problème ?
Claude.ai m'a proposé ces commandes :
