No sound on ASUS F3SC laptop with Ubuntu 7.04 or 8.04

Hi, thought I should share my problem - and the solution with the forum.

I assume, that you have checked that the speakers are not muted- OK - read on:

PROBLEM:
No sound after installing Ubuntu 7.10 (Gutsy Gibbon) on new ASUS F3SC laptop.

HARDWARE AND SOFTWARE DETAILS:

Kernel version:

Code:

jospan@discworld:~$ uname -r
2.6.22-14-generic

ALSA version:

Code:

jospan@discworld:~$ cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.14 (Thu May 31 09:03:25 2007 UTC).

The sound card:

Code:

jospan@discworld:~$ lspci -v | grep Audio
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)

The chipset on the sound card:

Code:

jospan@discworld:~$ cat /proc/asound/card0/codec#0 | grep Codec
Codec: Realtek ALC660-VD

Loaded sound driver:

Code:

jospan@discworld:~$ cat /proc/asound/modules
0 snd_hda_intel

SOLUTION:

Add the following line:

Code:

options snd-hda-intel model=lenovo

to the file /etc/modprobe.d/alsa-base (create the file if it does not exist)
..and yes: I know it says 'lenovo' and yes: I know my laptop is an ASUS!

Reboot and rejoice to the sound of the Ubuntu opening fanfare

Still no sound? - have you checked again that the speakers aren't muted? - Yes? - sorry, can't help you then...I'm the low-tech no-good son-of-newbie, remember?

By the way: I have also confirmed this solution when using Ubuntu 8.04 LTS (Hardy Heron) (ALSA driver 1.0.16) on the ASUS F3SC.
