Synchronous multi-room sound casting of Bluetooth, Airplay, Line-In and Spotitfy

Synchronous multi-room sound casting of Bluetooth, Airplay, Line-In and Spotitfy

ALL CREDITS TO @badaix AND @BaReinhard

This will setup a raspberry-pi-3 as a snapcast-server and snapcast-client.
Possible music sources for the snapserver-component: Bluetooth, Airplay, Spotify, Line-In (more to come eg. RTP)
Music sinks (snapclients): usb soundcard connected to my stereo, another Pi

To Do:

  • Energy saving by disabling onboard bluetooth, wifi and soundcard


Want to control a TV over HDMI-CEC via a remote RasPi? Include the following as a switch:

platform: command_line
      command_on: "ssh pi@<ip_address> -i /home/homeassistant/.homeassistant/id_homeassistant 'echo on 0 | cec-client -s -d 1'"
      command_off: "ssh pi@<ip_address> -i /home/homeassistant/.homeassistant/id_homeassistant 'echo standby 0 | cec-client -s -d 1'"

Linux kernel initialization, translated to bash
# Linux kernel userspace initialization code, translated to bash
# (Minus floppy disk handling, because seriously, it's 2017.)
# Not 100% accurate, but gives you a good idea of how kernel init works
# GPLv2, Copyright 2017 Hector Martin <>
# Based on Linux 4.10-rc2.
# Note: pretend chroot is a builtin and affects the current process
# Note: kernel actually uses major/minor device numbers instead of device name
