I would like to use Raspberry Pi 2 + HiFiBerry DAC+ together with Volumio.
At the moment, I don’t have the HifiBerry yet, thats why I am testing without.
Here is the Problem:
The volume control is very non-linear from 0 to 100%.
Between 0% and 80%, there is almost nothing to hear - very very silent.
Beginning with 80% the volume increases dramatically up to 100%.
I am using an iPhone for remote control, and it is very hard to control the volume in a sensible way via touchscreen, when I can only use the last 20%.
The curious thing is: When I use Pi Music Box instead of Volumio, it is perfect. But I love Volumio and I don’t want to give it up.
