It would be cool to have a button in the Gui that would switch a pin on the rpi, and we could remotely turn amps on or off (through a relay, of course). Would be useful for us with sweet diy amps without remotes.
better yet you could auto turn off amps (for us with crappy little digital amps) when the device isn’t playing anything, and turn them on with a configurable value before playback begins… would be awesome! power saving too!
