I have the issue that the volume of o zone (after a reboot) will go to MAX. I have the following hardware as a Roon Bridge running: Rapsberry Pi with HifiBerry Amp2 Audio Hat. It makes no difference which Rapsberry Pi Modell (2B or 3B) is used. Also no difference, if one “zone” has the original 7" display installed or not. After a reboot of the “Bridge” the volume resets to 100%!
I´m using the current Ropiee Image or the current DietPi Image with the corresponding AddOns - it makes also no difference.
Am I doing something wrong or is there any solution in sight?
