ode 0x08 [Audio Output] wcaps 0x41d: Stereo Amp-Out
  Control: name="Headphone Playback Volume", index=0, device=0
    ControlAmp: chs=3, dir=Out, idx=0, ofs=0
  Device: name="VT1802 Analog", type="Audio", device=0
  Device: name="VT1802 Alt Analog", type="Audio", device=2


the two devices cannot share   headphone audio output

when multistreaming playback,

alt analog device can play another audio stream for the headphone while
analog device play  audio stream on line out

did you disable independent headphone since it is a bug in hda_generic
to allow independent headphone when HP nid was put in multiout.dac  ?

HP should be put into multiout.hp
