No sound on Toshiba notebook with F16

Dopo aver aggiornato il mio portatile Toshiba a F16, l'audio è sparito. Per riavere l'audio ho dovuto aggiungere a:
/etc/modprobe.d/sound.conf
la riga:
options snd-hda-intel model=3stack

After upgrading to F16 my Toshiba notebook, the sound was gone. To get audio back I had to add to:
/etc/modprobe.d/sound.conf
the row:
options snd-hda-intel model=3stack
