toshiba_acpi on L670-1JN

According to :

http://memebeam.org/toys/ToshibaAcpiDriver

$ modprobe toshiba_acpi
FATAL: Error inserting toshiba_acpi
(.../kernel/drivers/acpi/toshiba_acpi.ko): No such device

means that I do not have the proper toshiba, in my case, here is what I got:

FATAL: Error inserting toshiba_acpi (/lib/modules/3.0.0-1-amd64/kernel/drivers/platform/x86/toshiba_acpi.ko): No such device

However if one dig a little further

$ sudo acpidump -b -t DSDT -o DSDT.aml
$ iasl -d DSDT.aml
$ grep TOS1900 DSDT.dsl
Name (_HID, EisaId ("TOS1900"))

Yay ! this means I should be able to use toshiba_acpi ! TOS1900 is the Toshiba Value Added Package from windows.

Intel [HDA Intel], device 0: ALC259 Analog [ALC259 Analog]

Finally got it to work, simply:

$ sudo vim modprobe.d/alsa-base.conf

then add:

options snd-hda-intel model=auto
options snd-hda-intel model=toshiba

after a :

$ sudo alsa force-reload

it should show a nice output now:
