I have a Dell Studio 15 which also uses snd-hda-intel. I see the same symptoms that the headphone socket turns off the main speakers but there is no output in the switching headphone socket. There is a second headphone socket in the machine which does not turn off the speakers, that ones does have sound. Very odd indeed.
