snd_hda_intel being in lum: Audio problems with D620

As it was suggested in Bug #131368 by Tim Gardner, I will open a new bug as it affects an other model.

I'm running Gusty on a DELL Latitude D620 notebook with a docking station. After the latest update (to 2.6.22-10-generic), I can only control the built-in speaker of the notebook -- a speaker connected to the docking stations stays mute. Before the updated, I couldn't control the volume of a speaker connected via the docking station, but at least it got an audio signal.

Additionally, I could choose whether the input-source is the built-in mic, an external mic or if it should act like an input line. This is gone now too.

To sum up, before the move of snd_hda_intel into l-u-m, I could:

   * control the volume of the internal speaker
   * had an audio signal on the docking station
   * could choose which kind of input source I had connected

After the move, I can only:

   * adjust the volume of the internal speaker
   * an external speaker connected to the docking station stays mute all the time
   * I cannot change the type of input source any more

N.B.: In windows, I can control the volume of a speaker connected to the docking station as well - I never could do this in linux, but I could live with it this way.
