I’m using a Pi B+ Model with Volumio 1.55 which is hooked to my amplifier with a standard 3.5mm jack to 2xRCA. When I try to change the volume through the WebUI, spotify-connect or sound@home the first 2/3 of the volume bar are pretty much silent. Only the last 1/3 is playing sound and the steps between different levels of volume are quite huge.
I did some troubleshooting by comparing the WebUI volume control to the one provided through AlsaMixer from the command line. It looks like this:
WebUI volume at 100 / AlsaMixer volume at 100
WebUI volume at 90 AlsaMixer volume at 67
WebUI volume at 75 / AlsaMixer volume at 24
So as you can see, the two controls are quite off. When I use AlsaMixer the changes are as smooth as they should be.
Is there a way to get both controls in sync?
Thx for your help!
