Do you let Volumio idle on RPi or do you shut it down?

I agree with the Mother Earth comment. I use a switch I bought from Audiophonics (https://www.audiophonics.fr/en/push-button/aluminium-push-button-and-pre-welded-connector-with-blue-light-circle-o19mm-black-p-11061.html and https://www.audiophonics.fr/en/raspberry-pi-and-other-sbc-accessories/audiophonics-pi-spc-v2-power-management-module-for-raspberry-pi-p-10912.html) and the accompanying plug-in (found in plug-ins menu) to switch my device on and off. Not only does it save electricity but it also makes the steamer feel like an authentic piece of hi-if equipment (Warp & Woof Signature T1). It only takes 30 seconds to boot - not too dissimilar to other branded Network Players I’ve owned previously.
