thats good, lets make the snapcast work then!
What took me some reading was the “tmp/snapfifo permission denied” error of snapserver. fixed by:
sudo echo "fs.protected_fifos = 0" | sudo tee /etc/sysctl.d/snapcast-unprotect-fifo.conf
other than that the above outlined steps should do it.
let us see erorr logs if you struggle.
