I followed those instructions and my computer is affected by what is described there. That is, I can see the "Headphone Output" appear and disappear from the list of outputs as I plug it in and unplug it. Likewise with the mic and list of inputs. I've noticed this since installing 12.04 and I like this feature because Skype "just works" now when I plug in my camera. Before it kept returning to the unused mic input even though there is no mic plugged in, so I would have to manually set it back the the camera mic input whenever I plugged in the camera. I no longer have to do that with 12.04 so I personally do not consider that a bug.
But what I am describing is slightly different and happened recently. The modification to the analog-output.conf.common file required for these Dell laptops causes the "Analog Output" to disappear just as the "Headphone Output" disappears when unplugged. It seems as though that modification has the same effect as "unplugging" the built-in speakers. Plus this just started happening Tuesday which is since that "bug" was reported.
