My Alpine MPD (Music Player Daemon) Lite

Table of Contents

Didn't get my hand dirty for a long time.

Music Player Daemon (MPD) is a flexible, powerful, server-side application for playing music. Through plugins and libraries it can play a variety of sound files while being controlled by its network protocol. - (

Above is a short description from MPD developer site. Indeed too short. MPD is powerful and feature rich. On one hand it has too many features I don't need. I just want a music player that can be control remotely. On the other hand the mpd package from Alpine repository some how has a high cpu usage and I have no clue how to debug it. Eventually I decided to just roll my own version and cut everything to the bare minimum.

meson configure output/release

ninja -C output/release

The binary is output/release/mpd. Move it to /usr/bin/.


Remove build tools and dev libraries:

apk del build-base boost ninja boost-dev meson alsa-lib-dev sqlite-dev ffmpeg-dev

Install Binary Dependency

Basically the non-dev version used during compilation.

apk add sqlite-libs alsa-lib alsa-utils ffmpeg


This is Linux “sound driver”. Use alsamixer to configure and un-mute the master volume.


My mpd.conf:

music_directory         "/home/<user>/.mpd/Music"
playlist_directory      "/home/<user>/.mpd/playlists"
log_file                "syslog"
pid_file                "/home/<user>/.mpd/"
state_file              "/home/<user>/.mpd/mpd.state"
sticker_file            "/home/<user>/.mpd/mpd.sticker"
user                    "<user>"
group                   "audio"
bind_to_address         "::"
port                    "6600"
log_level               "default"
auto_update             "yes"
database {
        plugin "simple"
        path "/home/<user>/.mpd/mpd.db"
audio_output {
        type            "alsa"
        name            "ALSA"
        auto_format     "no"
        auto_channels   "no"
        auto_resample   "no"

Must add <user> to group audio, else mpd cannot connect to alsa device.


MPD features is cut to the bare minimum, a music player that can be control remotely from my main desktop with GUI or cli, and from my phone. CPU usage remain ~2% when playing on my 10yrs old laptop.
