 Music in the space is controlled by a VM on [[projects:alford|Alford]] running MPD. [[User:hibby|hibby]] is responsible for this project. It used to live on a Pi, hence the name.

 Adding music to MPD is done via our anonymous FTP service on [[projects:alford|Alford]]!
+==== FTP ====
 It appears to be the fashion to make yourself a user folder, so if you don't have one, do that!

 You can also add tracks to your folder with an alternative application such as [[https://filezilla-project.org/|Filezilla]] which is an open-source (GNU GPL) (S)FTP client for Windows, Mac OS X and GNU/Linux.
+==== NFS ====
+Use NFS to mount ''alford.57north.org.uk:/usr/filestore/Music'' or ''172.23.152.9:/usr/filestore/Music'' if you're on our network.
 ===== Listening to the music =====
-The MPD audio plays directly out to the social room speakers. It also broadcasts on the space network via icecast. To listen in, use an icecast player (VLC works well) and play the following network address:
+==== Speakers ====
+Currently, the playback-pi is configured to play whatever mpd is pushing to snapcast.
+This is connected to the loudspeakers at the media workstation, on the audio switch input 1.
+==== Snapclient ====
+The mpd server uses [[https://github.com/badaix/snapcast|snapcast]] to broadcast audio to the network and ensure all players are in sync.
+On Debian, you only need to do the following while on our network to make your laptop sing in sync:
+<code># apt install snapclient </code>
+<code># systemctl start snapclient</code>
+To shut it up,
+<code># systemctl stop snapclient</code>
+==== HTTP Stream ====
+It also broadcasts on the space network via HTTP. To listen in, use an icecast player (VLC works well) and play the following network address:
     http://172.23.152.9:8000/Stream.m3u (Note the uppercase S)
+This will lag the snapcast stream by some undefined quantity of time.

+Snapcast is provided by [[https://packages.debian.org/stable/sound/snapserver|snapserver]] from Debian, and requires the following config in ''/etc/mpd.conf'':
