So this post is aimed at people who have a Dell Vostro 1400 and Ubuntu Gutsy installed.

When I got my new laptop I noticed that whenever I hibernated that I would lose my sound (but it would continue to work if I suspended). The work around that I found was to remove the kernel module and load it again and the sound would work. This turned out to be really annoying, so last night I decided to fix it.

It turns out all you need to do is install the linux modules backport package (like this):

sudo apt-get install linux-backports-modules-generic

Also make sure that

options snd-hda-intel probe_mask=1 model=3stack

is included in your /etc/modprobe.d/alsa-base file. So now your sound should work, now if only I could figure out how to make the second headphone plug work. If you happen to know please leave a comment.
