I would like to replace my aging Logitech Media Server which runs on Raspberry Pis and HiFiBerry DAC+ RCA Version with Amazon Raspberry Pi Echo as the players. I have got most of this to work using Echo multi-room but my whole house amplifier needs to be powered on and off depending is music is playing.
Currently I do this by picking up the hardware point on the HiFiBerry board that drives the "music playing" LED. This feeds an Arduino which n turn (after doing some other things) activates a relay and that powers up the amp. The Arduino also activates an RF remote that then powers up my two subwoofers and it all works beautifully and has done for 5 years, It never fails.
I am therefore dependent upon HiFiBerry to turn on my sound system. Without it, nothing will power up.
The long explanation over, my question: Can my HiFiBerrys be made to work with the Raspberry Pi Echo? If yes then I shall proceed with my changeover.
I use PiCorePlayer to feed audio to the amp and this has a HiFiBerry option. I have thus never setup a Raspberry Pi with a HiFiBerry from zero. That is why I am asking here.
Thanks in advance for your help.
