I can report another issue with the snd-hda-intel driver....I am using a 
Dell Vostro 1400 laptop and using the 159 kernel the lineout does not 
work.  If the speakers are plugged in, there is no sound whatsoever and 
I checked every possible mixer setting.  Unplugging the cable to the 
speakers, however, results in sound coming out of the laptop speakers 
after a noticeable pause.  Reverting back to the 134 kernel, these 
issues go away.
