Volume set below -27 db (35 per centage) makes Creative HS-720 absolutely silent

Description
Without pulseaudio volume level is detected correctly. (I 've changed default card in /etc/asound.conf, then ran speaker-test -c6 -twav
and set volume in alsamixer to 3 per centages)
With pulseaudio:
- Headset is loud, even on lowest possible volume level
- If I set volume below 35 per centages (below -27 db) the output becomes silent immediately.
- On some computers, there is possibility to change analog mode to digital (S/PDIF). With digital mode it becomes calmer: the loudest volume level produces low volume, it is the same as 35% of analog mode, and the lowest volume level may be still determined.
Tested with latest versions (ubuntu xenial): Version 7.1 kernel 4.4
