I managed to get it working again. It wasn't very simple, but I got 
myself a pile of new knowledge on the way, so I guess that the problem 
occuring was good in some sense.

I had to recompile the ALSA-driver and set it up once again. In my case 
it was the snd-hda-intel driver. From searching the internet there has 
been a lot of people having similar problems with this driver. If you 
are one of them do follow the steps outlined here:

It is a detailed an well written guide on how to solve various sound 
related problems.

Skål! (Cheers!)
