In Ubuntu 16.04.5 I have a (minor) issue with the Sound Settings.
I am hearing music from
mplayer with a USB headset. So far no problems.
But when I reduce the output volume below ca. 30%, there is no output volume at all anymore! It becomes completely quiet! When I increase the output volume, the music comes back.
This screenshots show the level for the output volume at which I am hearing music. Just a BIT lower and the sound is gone:
It would be nice if I could adjust the volume between 0% and 100%, and not just between 30% and 100%...
