[tlinux-users:08280] Re: Fixed - Satellite P100 Audio

It worked for my too. Here's a link to the Ubuntu bug report which

6.10 linux-source-2.6.17).

Thanks Chris for your help with this! And you're right - I'd love to
see Toshiba fix the DSDT in future BIOS releases so less technical
Linux users won't have to go without sound.
