There is another Dell XPS 9333 (201309-14238) with the same problem. I've double checked the workaround that cypressyew mentioned in comment #28 works with linux-image-3.11.0-18.
Also confirmed that this problem does not happen in linux- image-3.14.0-031400rc8 [0].

E g, for such a headset jack you can either plug in a headphone or a headset, but since the system cannot tell which one it is, you have to manually tell the system whether you want to use the internal or external mic. In the case of a headphone-or-mic jack, you can have the jack functioning as either a headphone or a mic, but not as a headset. Without this patch, PulseAudio would not detect the jack correctly, and not making all options available to the user. [Regression Potential] is very low: this only affects machines with the specific name "Headphone Mic Jack" or "Headset Mic Jack", which started to appear for a few machines in the 3.5 kernel. People who are running 12.04.0 or 12.04.1 will be unaffected. More machines are coming in the 3.10 kernel, so this is also a preparation for making certification easier later on. [Test case] On an affected machine, plug in something into the jack. Then go to "Sound Settings" and note what options there are: e g, for a headset jack, you should be able to select both external and internal mic manually.
