[alsa-devel] Support for ALC662 on FUJITSU SIEMENS AMILO Li3710

[Mads Kiilerich]

On a friends FUJITSU SIEMENS AMILO Li3710 10601011427 sound didn't work 
with kernel-PAE-2.6.29.6-213.fc11.i686

Out of the box we get no sound and
HDA Intel 0000:00:1b.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22
HDA Intel 0000:00:1b.0: setting latency timer to 64
hda_codec: Unknown model for ALC662, trying auto-probe from BIOS...

But with /etc/modprobe.d/local.conf (from 
http://ubuntuforums.org/archive/index.php/t-940689.html)
options snd-hda-intel model=3stack-dig
options snd-hda-intel single_cmd=1
options snd-hda-intel enable_msi=1

we get sound and
HDA Intel 0000:00:1b.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22
HDA Intel 0000:00:1b.0: irq 32 for MSI/MSI-X
HDA Intel 0000:00:1b.0: setting latency timer to 64
ALSA sound/pci/hda/hda_codec.c:2698: hda_codec: model '3stack-dig' is 
selected


I would like to have this fixed so Linux sound works on my friends 
machine without manual configuration.

After having read some documentation I assume that single_cmd and 
enable_msi perhaps shouldn't be needed. I will test that next time I get 
access to that machine.

HAL reports the sound card as 
/org/freedesktop/Hal/devices/pci_8086_293e, so should this patch be 
sufficient?

Untested and hard to test because I don't have direct access to the machine.
