Bonjour,
Comme indiqué dans le titre, je n'ai plus de son après migration vers la 20.04 (message : Aucun périphérique d'entre ou de sortie trouvé). Dans pavucontol :
sortie virtuelle
Cependant en live-usb 20.04 le son fonctionne parfaitement.
J'ai suivi la méthode proposée ici :
https://fluoblog.wordpress.com/2008/01/13/resolution-des-problemes-de-son-sous-ubuntu/ → message d'erreur.
Ensuite j'ai tente quelques manips de ce fil :

Et enfin celle-ci :

Je n'ai toujours pas de son

La carte semble détectée.
Dernier point qui me laisse dubitatif : si je connecte une enceinte Bluetooth j'ai du son sur celle-ci…
Grand merci à celle ou celui qui aurait une idée…
