Problème avec Realtek As'97

Bonjour,

Je n'ai plus de son sur mon PC. J'ai désinstaller le pilote Realtc'97 puis réinstaller un autre.
L'icone est barré sur la barre des taches. Quand je fait un clic droit dessus j'ai message volume 0.
Quand j'ouvre le mixeur de volume j'ai un message :"aucune périphérique détecté"

Quelqu'un a-t'il la solution ?
