Comment 81 for bug 438318

I finally got the external speaker working on my nb200-10g. I had to do this on lucid (ubuntu 10.4)

gksudo gedit /etc/modprobe.d/alsa-base.conf

When the file is open, please add the following 3 lines to the end of the file after "options snd-pcsp index=-2"

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=toshiba-nb200

Then open a terminal and do the following:

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34-rc1/linux-headers-2.6.34-020634rc1-generic_2.6.34-020634rc1_i386.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34-rc1/linux-headers-2.6.34-020634rc1_2.6.34-020634rc1_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34-rc1/linux-image-2.6.34-020634rc1-generic_2.6.34-020634rc1_i386.deb

sudo dpkg -i linux-headers-2.6.34-020634rc1_2.6.34-020634rc1_all.deb
sudo dpkg -i linux-headers-2.6.34-020634rc1-generic_2.6.34-020634rc1_i386.deb
sudo dpkg -i linux-image-2.6.34-020634rc1-generic_2.6.34-020634rc1_i386.deb

if grub2-update doesn't automatically run after the last command then do sudo update-grub

reboot and you should have sound (if you like me have been messing with the outputs in the volume control you might need to open it up and select Speakers [ i only had headphones and output before doing this])

I am currently listening to "Yazoo - Only You" through the external speakers (probably shouldn't have botherd ;)
