Before this I tried the "laptop" mode and the "generic" one, both of which
did not work.

You don't need any model since the pin defaults of your Intel DG41CN  are
correct unless you want to use CD audio in connector

You should check the front audio panel of your computer chassis if jack
state of headphone is alway plugged

http://fedoraproject.org/wiki/How_to_debug_PulseAudio_problems

You have to provide pulseaudio verbose log

Default setting support multi channels but NO headphone playback volume
control

http://www.intel.com/support/motherboards/desktop/sb/CS-034198.htm

You can disable multi channels by using early patching and hint multi_io=0
to get back the headphone playback volume control

- multi_io (bool): try probing multi-I/O config (e.g. shared
  line-in/surround, mic/clfe jacks)
