HifiBerry DAC and USB DAC + Volumio2 volume doesn't work ?!

Hey, I recently install Volumio 2 on my Raspberry 3 but I got a little problem. The volume doesn’t work.
I try with different DAC (Hifiberry and USB DAC) but it’s the same problem.

Let my now if you got an idea.

Hi, I have the very same problem - would be great if somebody could give any advice. Turning volume knob doesnt change anything, volume stays at 100%.

Greetings!

This is a known issue and will be fixed by the team in the near future.
