you may try to clear misc bit of pin default of 0x1e so that the driver create a hda jack kcontrol

Define a customised alc663_unsol_event() to handle the unsolicited event fron the pin complex 0x1e

Misc = NO_PRESENCE

  Pincap 0x00000014: OUT Detect

    Conn = ATAPI, Color = Unknown
    DefAssociation = 0x2, Sequence = 0x0
    Misc = NO_PRESENCE
  Pin-ctls: 0x40: OUT
