I have a toshiba l35 laptop and everything pretty much worked.(had a little confusion getting my ati 200m card working but managed to figure it out. Solution here:
The other potential big head ache was my headphones. Luckily I already knew how to fix it from last time(but the process is a little easier now).
Open terminal and paste in this:
Then paste this into the notepad that comes up
sudo gedit /etc/modprobe.conf
Save it and then reboot.
options snd-hda-intel model=6stack-digout
After the reboot double click the sound icon in the upper right and then enable all of the controls in options. My headphones were linked to the surround one.(may be different for you I guess)
