dmesg: échec de lecture du tampon de noyau: Opération non permise
VLC montre la vidéo mais aucun son.
Lorsqu’il n’y a pas de lecture de son ou de vidéo, on entend un léger grésillement dans les diffuseurs.
Quand je lance la lecture d’une vidéo ou d’une bande son, il y a un petit « tic » dans les diffuseurs et plus rien. Le silence complet jusqu’au moment où je stoppe la lecture. Le grésillement revient alors.
Merci pour ton aide.
