Since installing subsonic is so easy to set up, I looked for another challenge: MPD.
I tried to use Rhythmbox and Banshee as players on my computer dedicated for audio outputs. If the music is located elsewhere on the LAN, both ended up unable to index 100+Gb music, and since I do not like their GUI anyway, I found out another possible solution with MPD.
Installing and setup for Ubuntu 11.10
1. Install
sudo apt-get install mpd mpc gmpc
This will retrieve mpd together with the command line player mpc and the Gnome client gmpc, for those GUI users.
2. Configure
Some guides I found (most of them) explain how to set up mpd on a system using root rights. I preferred to get everything installed for my current user, mainly to be easier to port to another installation later on, and also because I just like simple backup from user home directory. So instead of following guides creating a mpd directory on /var/lib and using a /etc/mpd.conf, I choose to create a mpd directory under the home directory, and use a .mpdconf file.
Following commands are enough to create required directories and starting with a new configuration file.
cd ~
mkdir mpd
mkdir mpd/playlists
gedit .mpdconf
Here is my configuration file (.mpdconf). The music_directory and the playlist directory should exist, according to previous commands.
# Files and directories #######################################################
#
# This setting controls the top directory which MPD will search to discover the
# available audio files and add them to the daemon's online database. This
# setting defaults to the XDG directory, otherwise the music directory will be
# be disabled and audio files will only be accepted over ipc socket (using
# file:// protocol) or streaming files over an accepted protocol.
#
music_directory "~/Music"
#
# This setting sets the MPD internal playlist directory. The purpose of this
# directory is storage for playlists created by MPD. The server will use
# playlist files not created by the server but only if they are in the MPD
# format. This setting defaults to playlist saving being disabled.
#
playlist_directory "~/mpd/playlists"
#
# This setting sets the location of the MPD database. This file is used to
# load the database at server start up and store the database while the
# server is not up. This setting defaults to disabled which will allow
# MPD to accept files over ipc socket (using file:// protocol) or streaming
# files over an accepted protocol.
#
db_file "~/mpd/mpd_db"
#
# These settings are the locations for the daemon log files for the daemon.
# These logs are great for troubleshooting, depending on your log_level
# settings.
#
# The special value "syslog" makes MPD use the local syslog daemon. This
# setting defaults to logging to syslog, otherwise logging is disabled.
#
log_file "~/mpd/mpd.log"
#
# This setting sets the location of the file which stores the process ID
# for use of mpd --kill and some init scripts. This setting is disabled by
# default and the pid file will not be stored.
#
pid_file "~/mpd/pid"
#
# This setting sets the location of the file which contains information about
# most variables to get MPD back into the same general shape it was in before
# it was brought down. This setting is disabled by default and the server
# state will be reset on server start up.
#
state_file "~/mpd/state"
#
# The location of the sticker database. This is a database which
# manages dynamic information attached to songs.
#
sticker_file "~/mpd/sticker.sql"

# General music daemon options ################################################
#
# This setting specifies the user that MPD will run as. MPD should never run as
# root and you may use this setting to make MPD change its user ID after
# initialization. This setting is disabled by default and MPD is run as the
# current user.
#
#user "mpd"
#
# This setting specifies the group that MPD will run as. If not specified
# primary group of user specified with "user" setting will be used (if set).
# This is useful if MPD needs to be a member of group such as "audio" to
# have permission to use sound card.
#
#group "nogroup"
#
# This setting sets the address for the daemon to listen on. Careful attention
# should be paid if this is assigned to anything other then the default, any.
# This setting can deny access to control of the daemon. Choose any if you want
# to have mpd listen on every address
#
# For network
bind_to_address "localhost"
#
# And for Unix Socket
#bind_to_address "/var/run/mpd/socket"
#
# This setting is the TCP port that is desired for the daemon to get assigned
# to.
#
port "6600"
#
# This setting controls the type of information which is logged. Available
# setting arguments are "default", "secure" or "verbose". The "verbose" setting
# argument is recommended for troubleshooting, though can quickly stretch
# available resources on limited hardware storage.
#
#log_level "default"
#
# If you have a problem with your MP3s ending abruptly it is recommended that
# you set this argument to "no" to attempt to fix the problem. If this solves
# the problem, it is highly recommended to fix the MP3 files with vbrfix
# (available as vbrfix in the debian archive), at which
# point gapless MP3 playback can be enabled.
#
#gapless_mp3_playback "yes"
#
# This setting enables MPD to create playlists in a format usable by other
# music players.
#
save_absolute_paths_in_playlists "no"
#
# This setting defines a list of tag types that will be extracted during the
# audio file discovery process. Optionally, 'comment' can be added to this
# list.
#
#metadata_to_use "artist,album,title,track,name,genre,date,composer,performer,disc"
#
# This setting enables automatic update of MPD's database when files in
# music_directory are changed.
#
auto_update "yes"
#
# Limit the depth of the directories being watched, 0 means only watch
# the music directory itself. There is no limit by default.
#
#auto_update_depth "3"

###############################################################################
# Symbolic link behavior ######################################################
#
# If this setting is set to "yes", MPD will discover audio files by following
# symbolic links outside of the configured music_directory.

# If this setting is set to "yes", MPD will discover audio files by following
# symbolic links inside of the configured music_directory.

Running MPD
Now it is already time to hear some music!
Just enter following in your terminal:
mpd
Yes, this is all!
Running the gnome MDP client
Once the client is running, in the Server-menu, there is an Update entry. This will populate the music database with data found under the ~/Music directory, and music will be shown in the left panel. From here, it is easy to get music played.
Problems?
Note that if all sounds easy, it is also easy to miss a small part of these steps, and no music will be played. There is some things to check, in order to find out possible problems.
- Check that sound is working, using Rhythmbox for example, and playing a local music file.
- Check that all pathes are correct. A wrong path to the music will be problematic for mpd to find any music. A non existing path for the database file will also be problematic to populate the database with content.
- Still no music? Using Ubuntu Unity, I could play without problem the music, but not under XFCE. This was because of muted sound on the login screen!
Bonus: Client175
Now, once MPD is running smoothly on the audio box, perhaps (probably) one would like to control the music from other devices.
There is a huge list of clients for MPD here: http://mpd.wikia.com/wiki/Clients.
However, some of them are old/abandoned/unfinished projects. This requires a bit of searching to get the one(s) you like.
A simple web access can be achieved using Client175. The setup does not require anything to run correctly (based on my .mpdconf). I just created a folder for the client175 files under my mpd directory, and started it with python server.py. Then accessing from another box with your prefered browser is enough to enjoy it (default port is 8080, not to forget when trying to connect ;) ).
