Forum Ubuntu-it

ciao a tutti.

ho installato sul mio pc fisso (P4 2.0Gh-768Ram-scheda audio integrata-Ati Radeon x1600 pci Express)  ubuntu 10.04 e ubuntu studio 10.04 e ora non viene rilevata la scheda video e audio.
su questa macchina ho anche WIN XP e li l'audio e video funzionano regolarmente. ::)

su questo pc c'era debian e funzionava tutto e prima ancora ubuntu 8/9.04 e 9.10 e l audio e video son sempre stati riconosciuti e funzionavano regolarmente.

qualcuno ha lo stesso problema? come posso risolvere?

da terminale vedo questo:

ubuntu:~$ alsamixer -V all
impossibile caricare i controlli del mixer: Argomento non valido

e

Ciao,

da terminale copia e incolla l'output di questi comandi:

sudo aplay -l

lsmod | grep snd

cat /proc/asound/cards

cat /dev/sndstat

così vedo come è impostata la scheda audio.

Lo faccio io che ho lo stesso problema!

Ciao,

apri il terminale e digita questo comando (in rosso):

sudo gedit /etc/modprobe.d/alsa-base.conf

aggiungere questa riga:

options snd-hda-intel model=mobile

salvare e chiudere l'editor di testo.

Sempre da terminale dai questo comando (in rosso):

sudo gedit /etc/modprobe.d/options

aggiungere questa riga:

options snd-hda-intel model=mobile

salvare e chiudere l'editor di testo.

digitare questo comando (in rosso):

sudo alsactl store

chiudere il terminale.

Riavviare il pc.
