there are two amp at node 0x16 and 0x1a in green line out Jack path from
node 0x10 to node 0x1a
dB range is sum of pcm playback volume and front playback volume
not sure why pulseaudio use 8.5dB as Max since dB Max of pcm playback
volume is 14 dB

Title:
Pulseaudio does not recognize sound levels correctly.
Status in PulseAudio sound server:
Fix Released
Status in “pulseaudio” package in Ubuntu:
Confirmed
Bug description:
When I am setting volume to 75-100% sounds is amplified and quality is very
bad.
Setting for "Unampified" in sound settings (which is placed around 50% of the
bar) makes sound is almost unhearable.
Sound is good and loud around 60% of volume. This is really annoying
because setting volume from keyboard or sound indicator is useless ->
volume up makes terrible sound, volume down only 10% to
50%(unamplified) makes there is almost no sound.
