<pre>You have to post pulseaudio verbose log
control.1 {
iface MIXER
name 'Front Playback Volume'
value.0 64
value.1 64
comment {
access 'read write'
type INTEGER
count 2
range '0 - 64'
dbmin -6400
dbmax 0
dbvalue.0 0
dbvalue.1 0
}
}
dBmin of those playback volume controls are -64dB
virtual master playback volume is present on both headphone path and line out
path
it depend on pulseaudio adjust which volume control first

you can try comment volume of [Element Master] from headphones.conf and
lineout.conf and observe the difference
[Element Master]
switch = mute
#volume = merge
override-map.1 = all
override-map.2 = all-left,all-right
