[tlinux-users:08278] Re: Fixed - Satellite P100 Audio

Hi Chris,
So I did the following:
- disassembled dsdt,
- modified the code,
- made it compile,
- added the dsdt.hex file to my 2.6.17 kernel,
- built the kernel,
- created an initrd image with mkinitrd --dsdt=dsdt.ml
- updated lilo.conf
- restarted with the new kernel
- updated alsa-drivers, alsa-lib, and alsa-utils to 1.0.14-rc1

But no sound =(
Mine is a PSPA3C-JR100E
