Last week, i have installed Linux on my laptop, and i had the same problem....
After long days of research i have find that i should patch my kernel (2-4-18) with ACPI (you could find this patch on http://sourceforge.net/projects/acpi ). Finally i have installed a kernel 2.4.19 (because on my laptop, the patch didn't really work... :( ) and compile it with ACPI support, and it work !!!! I have sound. I have a SoundMAX Integrated Digital Audio with ALSA.... but for the moment it's a Mandrake 9.0 :( because it include a 2.4.19 kernel... I will try with a Debian.... Have fun :) and sorry for my english... i'm french :) Etienne >Messsage du 02/10/2002 13:38 >De : Ivan Uemlianin <[EMAIL PROTECTED]> >A : <debian-laptop@lists.debian.org> >Copie à : >Objet : Trying to get sound working ... > > > > Dear All > > I'm running Debian Woody on an IBM Thinkpad A31p.
