I am very sorry, as i have now the manual of your machine, and i want to confirm that your machine is using SiS chipset and not intel.
Major problem: Sis hates linux, and therefore, Linux hates Sis. I mean Silicon Integrated Systems are one of those blamed company by the opensource community cause they DO NOT disclose hardware specs, so nobody can properly write a driver for it, apart Microsoft, which off course has the specifications by commercial contract. Sis as well makes these 'AL integrated' Chipset that holds a lot of things ( sound, ethernet and video ).
So the only thing left is reverse engeneering, and this is the way for example a SIS 650 AGP video card now works properly on linux.
Anyhow the situation is now 100 times better as it was 2 or 3 years ago. So i have lots of hopes for your sound.
Anyhow this looks a similar situation :http://sdb.suselinux.hu/en/sdb/html/...ecs_k7s5a.html
The solution once again reside in Alsa sound drivers. Here is your solution :http://www.alsa-project.org/alsa-doc...odule=intel8x0
SO get to the www.alsa-project.org
page, and download the driver, lib, tools and utils packages of the 0.9rc8 or latest branch. DO NOT USE THE STABLE series 0.5 as it is deprecated, unmaintainned and unsupported, so it will NOT work. There is several how tos on the site, follow them step by step, and your sound will work
If you have big troubles, post it here and if you can chat on IRC, i will help you step by step. Cannot do this for everybody btw
