(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: 1) Headset is loud, even on lowest possible volume level 2) If I set volume below 35 per centages (below -27 db) the output becomes silent immediately. 3) 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.

Setting volume over 100% causes overdrive (headset may play louder without overdrives according to my past expirience). Maybe making such config default is good idea? (replace merge with ignore) 2) I 'm using windows-dualboot and I have noticed that 100% volume on windows is always louder that 100% on linux (with PA) 3) In which file should I place "ignore_db=1"? 4) Is it dangerous to recalibrate my headsets? Should I use any program (I don't know which) to provide range which I consider correct? And which units should I use ? (dB, volts, some virtual usb units etc.) I guess such patches should be sent to alsa project or kernel, not PA.

"load-module module-udev-detect use_ucm=0 ignore_dB=1" in /etc/pulse/default.pa is far better solution. The volume may be still extreme loud, but I won't set it over 45%. >From all above I conclude: 1) It's not PA fault, but some default configurations may be altered in pulseaudio. Why not to make ignore_dB=1 default? 2) According to latest comment here: https://chrisjean.com/fix-for-usb-audio-is-too-loud-and-mutes-at-low-volume-in-ubuntu/ On some architectures (amd64) or most motherboards creative and some other cards are too loud, and I should have talks with kernel devs with this problem Reply at: https://bugs.launchpad.net/ubuntu/+source/alsa- driver/+bug/1534929/comments/17 ------------------------------------------------------------------------ On 2016-02-10T09:32:17+00:00 Raymond wrote: 1.814| 0.000) I: [pulseaudio] alsa-sink.c: Hardware volume ranges from -28,37 dB to -0,06 dB.

Setting to above ~40 % restores playback volume to what you would expect. In alsamixer, the same problem occurs when going from volume level 02 to volume level 01. At alsamixer level 02, the volume is about what you would expect when setting a volume slider to about 40 %. This is annoying since 40 % can already be rather loud.
