Il problema è iniziato entro il 12.10. Prima ha funzionato perfettamente. Ora, anche il riavvio di alsa non funzionerà, devo riavviare.
Per favore, chiedi dettagli. Sto eseguendo Ubuntu 12.10, unità DE con gnome 3.6, nessun driver di terze parti.
Grazie
Eccoti qui con l' sudo lshw

Ho provato a rimuovere e leggere il modulo del kernel audio - comunque
Non posso sudo modprobe -r snd_hda_intel
. DàFATAL: Module snd_hda_intel is in use
Eccoti con il /etc/modprobe.d/alsa-base.conf
