Node 0x11 [Audio Selector] wcaps 0x30010d: Stereo Amp-Out
  Amp-Out caps: ofs=0x17, nsteps=0x1f, stepsize=0x05, mute=1
  Amp-Out vals:  [0x17 0x17]
  Connection: 1
     0x03


when loopback mixing is enabled, the current driver remove the previous
"PCM playback volume" and set the amp at 0dB which is 12 dB lower than the
previous version
