--- Comment #10 from Raymond <superquad.vortex2 at gmail.com> ---
Node 0x02 [Audio Output] wcaps 0x41d: Stereo Amp-Out
  Control: name="Speaker Playback Volume", index=0, device=0
    ControlAmp: chs=3, dir=Out, idx=0, ofs=0
  Device: name="ALC892 Analog", type="Audio", device=0
  Amp-Out caps: ofs=0x40, nsteps=0x40, stepsize=0x03, mute=0
  Amp-Out vals:  [0x40 0x40]


alc892 has 64 steps with 1 dB per step

it is strange that pulseaudio hardware volume at -1.2dB

ulseaudio] alsa-sink.c: Got hardware volume: 0:  96% 1:  96%
D: [pulseaudio] alsa-sink.c:               in dB: 0: -1.20 dB 1: -1.20 dB
