salve a tutti…qualcuno mi saprebbe spiegare come fare ad ascoltare l’audio in cuffia?quando inserisco il jack non esce alcun suono(premetto che le cuffie funzionano perfettamente)ho provato a leggere i vari post ma non ci ho capito un granche’…l’audio funziona perfettamente con le casse interne del pc(ho un portatile packard bell easynote).
grazie.

facciamo una prova, da root:
# gedit /etc/modprobe.d/alsa.confinserisci la linea:
**
options snd-hda-intel model=lenovo-nb0763**
salva, chiudi, restart sistema, testa l’audio e le cuffie.
niente…tutto come prima…
prova anche questa:
