Public bug reported: Volume seems to work fine on the built-in laptop speakers (4 of them). When headphones are plugged in (two stereo headphone outputs), volume cuts to zero once the 16% level is reached in Master channel (as seen in alsamixer).
I suspect that the headphones are not properly detected/setup, because I have no "analog headphones" profile to choose in pavu/sound settings, as I heard some other people have. This seems to be similar to the issue described at http://ubuntuforums.org/showthread.php?t=1850159 (different hardware, but a similar two headphone plugs hardware), and partially with the issue described in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/429844 The solutions presented (ignore_dB=1, channel=PCM etc.,) didn't work.
