Volume stuck after 31

Volumio Information

Volumio Version: 2.779
Hardware: raspberry pi 3 b+
DAC: hifiberry amp2

Hi in settings “playback” i have changed the value for “Volume per click” to 1.
The problem up to 31 it works fine after 31 it stuck.

Change the volumer per click setting back to the default?

that is not the problem but i would like to use it like that. The question is whether this is just me or is a bug

Try to set volume curve to logarithmic

i try this settings and it works thank you
