Multi Room Audio Configuration

Multi Room Audio Configuration

# if you intend to create a multi-room audiophile configuration sharing the same music library on your LAN network
# Use the script below to configure your audio server very easily.
# change the hostname manually

# in Edition 2021 raspotify config (/etc/default/raspotify)
# and docker spot image must be changed as well, see the script 2021 below

---

# change hostname by script
# create the script in scripts directory

# we suggest a name which identify the room easily like a Music or Audio prefix + the room name (e.g MusicBedroom, MusicLivingroom, MusicKitchen,…)
# run the script with the audio server name in parameter, example:

# type y to reboot the server
# that’s it!
