All right, auto mute disabled.

When Independent HP is enabled I can hear nothing through the
headphone:

speaker-test  -c2 -t wav -D hw:0,2

speaker-test 1.0.25

Playback device is hw:0,2
Stream parameters are 48000Hz, S16_LE, 2 channels
WAV file(s)
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 64 to 524288
Period size range from 32 to 262144
Using max buffer size 524288
Periods = 4
was set period_size = 131072
was set buffer_size = 524288
 0 - Front Left
 1 - Front Right
Time per period = 5.487935
 0 - Front Left
 1 - Front Right
Time per period = 5.469224
 0 - Front Left
 1 - Front Right
Time per period = 5.469168
 0 - Front Left
 1 - Front Right
Time per period = 5.469292
 0 - Front Left
 1 - Front Right

and so on...


When HP Independent is disabled I hear the same through front speaker
and headphone, just as expected.

alsa-info.sh output is attached.
