This is not a bug in hardware. This is rather a weird feature: In some soundcards PCM chanel gain range is not -X~0, but rather -X~+Y. A kind of digital boost.
On my Realtek NVidia CK804 range of PCM chanel is -34.5~12.0. So it must not be set on maximum in normal circumstances, but rather is to be set to 0 (74%).
I wonder why pulseaudio should mess with PCM chanel when changing master volume.
...but i do not really care, because I do not use pulseaudio, and another nasty bug is relevant to me: https://bugs.launchpad.net/ubuntu/+source/gnome-media/+bug/440465
