Title:
Pulseaudio does not recognize sound
I want to note that update to the latest alsa-driver have fixed all my
problems.
Now sound is good in all scale 0-100%, and scale is proportionally - on
10% I have very quiet sound, and on 100% I have 100% loud volume that is
not distorted (0dB gain on master and PCM)
Thank you @Raymond for your

has_dB=yes, min_volume=0, max_volume=27, min_dB=-87.5, max_dB=8.5
have you ask the pulseaudio developer how to calculate Max_dB ?
min_dB=-87.5 = (-47.25) + (-40.45) = front + pcm

You received this bug notification because
-40.25 + (31 * 1.75) = 14
-40.25 + (27 * 1.75) = 7
how pulseaudio obtain max_dB=8.5 ?

In my case the same - Ii looks that it has been fixed. (Although I did not
remember any update - but I might miss that because I call updates
automatically when they appear).
Now on 100% of volume I have 100% of Master and 100% of PCM, and PCM on 100%
has only 1,75dB gain. And on 100% it makes

Hmm, but that argument chooses a card number, nothing changes in
display. So I had not seen label with dB earlier. Sorry ;-)

did you follow the instruction to disable autospwan and kill pulseaudio
pulseaudio -v and change the slider in sound preference from Max to
min
and provide log similar to Symptom_PulseAudioLog.txt in
open terminal and run alsamixer -c0 to monitor the dB OF PCM PLAYBACK
VOLUME CONTROL by using right arrow to select pcm playback volume when
you change the slider of sound preference

I do not know how many PCM dB is when sound is getting distorted - but
it is more that 50 (is this %? ) in unit which is presented in alsamixer
below the bar.
I cannot generate the log because I have not ~/.pulse dir in my Homedir, so I
can set autospawn = no.
Should I seek it in /etc or /usr
so I can not set *

Sorry for delay in response, I was offline.
I was monitoring values in alsa mixer, and this is a result:
1) The place in the bar then sound is good quality and able to hear is on

With Master - 100%
PCM 50-60%
2) When reduce volume to Unamplified (Bez wzmocnienia)
https://wiki.ubuntu.com/PulseAudio/Log
since pcm playback volume has a 14dB gain
do you mean that you have distorted sound when pcm playback volume is
over 0dB ?

the pcm playback volume control at audio mixer 0x16 has different dB
range and is common to headphone and line out, this mean that virtual
master should not use is as slave
use alsamixer -c0 to monitor the change in volume controls when you
change the slider in sound preference
