Bonjour,
J’ai mis mon Debian à jour hier soir et, depuis, je n’ai plus de son. Pourtant, quand je teste sur mplayer ou vlc, je n’ai aucun message d’erreur, et speaker-test fonctionne. Je vous rassure, le son n’est pas coupé, et je le prouve :
# amixer -c 0 get Master
Simple mixer control 'Master',0
Capabilities: pvolume pvolume-joined pswitch pswitch-joined penum
Playback channels: Mono
Limits: Playback 0 - 64
Mono: Playback 37 [58%] [-20.25dB] [on][/code]
Voici les informations qui me semblent pertinentes, et excusez-moi si j'en oublie.

J’ai fait tous les forums et je n’ai rien trouvé. J’ai désinstallé et réinstallé ALSA, j’ai testé avec et sans pulseaudio.
Merci d’avance pour votre aide !
