# Software

Components:

*   mopidy 
*   snapcast 
*   shairport-sync 
*   upmpdcli

## mopidy

## snapcast

Install snapclient on all media player nodes:

Releases
:   <https://github.com/badaix/snapcast/releases>

Server
:   [amd64 deb][48]

Clients
:   [Android][49], [RPi][50]

No iOS equivalent?

Note that snapclient on volumio is symlinked to `/usr/sbin/snapclient`. The default snapclient is very old (~0.2) and won't work with recent snapservers (0.11+).

### Snapserver config

*   Don't daemonize. systemd does it for you. 
*   Use the same or separate streams for mopidy and airport? 
*   Depends on `librespot@.service` templates for multiple instances of librespot service

`/etc/defaults/snapserver`:

USER_OPTS="--user snapserver:snapserver"
    
    SNAPSERVER_OPTS=" \
        -s 'pipe:///tmp/snapfifo0?name=Mopidy&sampleformat=44100:16:2&codec=flac' \
        -s 'pipe:///tmp/snapfifo1?name=Airport&sampleformat=44100:16:2&codec=flac' \
        -s 'pipe:///tmp/librespot1?name=Spotify-1&sampleformat=44100:16:2&codec=flac' \
        -s 'pipe:///tmp/librespot2?name=Spotify-2&sampleformat=44100:16:2&codec=flac' \
        -s 'pipe:///tmp/librespot3?name=Spotify-3&sampleformat=44100:16:2&codec=flac' \
    
    "

### Multi-instance snapclient systemd service

`/etc/systemd/system/snapclient@.service`:

# Multi-instance snapclient service file
    [Unit]
    Description=Snapcast client
    After=network-online.target sound.target
    Requires=network-online.target
    Wants=avahi-daemon.service
    
    [Service]
    # Uses a per-instance defaults file to specify the soundcard device
    EnvironmentFile=-/etc/default/snapclient-%i
    Type=forking
    ExecStart=/usr/bin/snapclient -d $USER_OPTS -i %i $SNAPCLIENT_OPTS
    PIDFile=/var/run/snapclient/pid-%i
    Restart=always
    
    [Install]
    WantedBy=multi-user.target

`/etc/default/snapclient-x`:

# Legacy?
    START_SNAPCLIENT=true
    
    USER_OPTS="--user snapclient:audio"
    SNAPSERVER_HOSTNAME=media
    
    # Don't specify -i here, it's added by the systemd service
    # RPi HDMI soundcard
    SNAPCLIENT_OPTS="-h $SNAPSERVER_HOSTNAME -s CARD=ALSA,DEV=1"

Install with:

sudo systemctl enable snapclient@1
    sudo systemctl enable snapclient@2
    ...etc..

## librespot

Spotify daemon.

### Multi-instance librespot systemd service

Depends on snapserver. Using TCP ports 22120-22129.

`/etc/systemd/system/librespot@.service`:

[Unit]
    Description=Librespot
    Requires=snapserver.service
    After=network.target storage.target snapserver.service
    
    [Service]
    #EnvironmentFile=/etc/default/librespot
    User=snapserver
    Group=audio
    Restart=always
    RestartSec=10
    PermissionsStartOnly=true
    Environment="CACHE_DIR=/path/to/librespot-cache"
    
    ExecStartPre=/bin/mkdir -m 1755 -p ${CACHE_DIR}/%i
    ExecStartPre=-/bin/chown snapserver:audio ${CACHE_DIR}/%i
    
    # Create the fifo for snapserver to read
    ExecStartPre=-/usr/bin/mkfifo /tmp/librespot%i
    ExecStartPre=-/bin/chown snapserver:audio /tmp/librespot%i
    
    Environment="DEVICE_NAME=Spotify-%I"
    Environment="BITRATE=96"
    Environment="CACHE_ARGS=--cache ${CACHE_DIR}/%i"
    Environment="VOLUME_ARGS=--enable-volume-normalisation --linear-volume --initial-volume=100"
    Environment="BACKEND_ARGS=--backend pipe --device /tmp/librespot%i"
    ## Abuse the instance ID to open a known port (for firewalling)
    Environment="ZEROCONF_ARGS=--zeroconf-port 2212%i"
    ExecStart=/usr/local/bin/librespot --name ${DEVICE_NAME} $BACKEND_ARGS --bitrate ${BITRATE} $CACHE_ARGS $VOLUME_ARGS $ZEROCONF_ARGS $OPTIONS
    
    [Install]
    WantedBy=multi-user.target snapserver.service

Install with:

sudo systemctl enable librespot@1
    sudo systemctl enable librespot@2
    ...etc..

## shairport-sync

## upmpdcli

Available for armhf Jessie-based Volumio but not for Stretch-based OSMC.

Packages available from: <https://www.lesbonscomptes.com/upmpdcli/downloads.html#debian>

### Install

# Depends on libjsoncpp0:
    echo "deb http://archive.raspbian.org/raspbian/ jessie main contrib non-free rpi" >> /etc/apt/sources.list.d/raspbian.list
    apt-key adv --keyserver pool.sks-keyservers.net --recv-keys F8E3347256922A8AE767605B7808CE96D38B9201
    echo "deb http://www.lesbonscomptes.com/upmpdcli/downloads/raspbian/ stretch main" > /etc/apt/sources.list.d/upmpdcli.list
    apt-get update
    apt-get install upmpdcli

### Configure

Edit `/etc/upmpdcli.conf` (and for Volumio, copy it to /tmp/upmpdcli.conf):

Two settings needed:

friendlyname = my-hostname
    upnpiface = eth0  # or wlan0, or whatever
