I have been using Volumio for a year now, great software.
But i have some issue, or not.
Version installed juli-2017 did have double volume controls, one in volumio and one in airplay. If volumio volume control was 25% my volume was 0-25% wich had some features. To limit the kids from playing to loud, and my wife also…
After update now airplay volume is master. Thats okay. Simpler. But before the total max volume was higher, it could play disco with a just boom amp. Feels like a lost 50% of max power.
