That's correct, PCM behaves always the same way (with or without patch).

I mean value which is under Master control bar in alsamixer program.

I have exactly the same behavior of volume control as you described, but after
applying ad1981-hp-master-amp-fix master behaves as described in previous
letter and below (as reminder).
"I can only decrement it (master) to value (I've described what do I mean
saying "value" in the begining of the letter) 3, and when I press
down key (in alsamixer) to step to lower level of loudness, it's switching to
value 103. When Master has 103 value I can hear very quiet output from
internal speakers and HP (if plugged)."
