The bisect done on HSW lead to:

    ALSA: hda - hdmi jack created based on pcm

    Jack is created based on pcm.

    Apply the acomp jack rule to dyn_pcm_assign.
    For dyn_pcm_assign:
     Driver does not use hda_jack. It operates snd_jack directly.
     snd_jack pointer will be stored in spec->pcm.jack instead of
     the current spec->acomp_jack. When pcm is assigned to pin,
     jack will be assigned to pin automatically.
    For !dyn_pcm_assign:
     Driver continues using hda_jack for less impact on the old cases.
     Pcm is statically assigned to pin. So is jack. spec->pcm.jack
     saves the snd_jack pointer created in hda_jack.
