Fixing the sound on Dell's XPS 17 9700 on Linux
Dell's new XPS 17 line includes a new hardware array of microphones. That's cool, but it's not supported on most Linux distributions yet.

And even worse, on current Ubuntu default installations it causes sound output to break completely.
The way to fix this is to update your kernel to a version that supports this new hardware and then install the necessary firmware and drivers. Since any system update can break this fix again I decided to wrap it up into a small script that does most of the work for you.
Now we can all have our... sound and update our systems too.
