Advanced MPD Configurations: Networking, Caching, and Performance Tweaks
Overview
- Focus: MPD (Music Player Daemon) advanced settings to improve network access, caching, and playback performance on servers and embedded devices.
- Assumes MPD >= 0.21 and a Linux host with systemd. Paths and user/group: /etc/mpd.conf, user mpd, music directory /var/lib/mpd/music (adjust to your system).
1. Safe baseline: backup and permissions
- Backup current config and DB:
Code
sudo cp /etc/mpd.conf /etc/mpd.conf.bak sudo cp /var/lib/mpd/tag_cache /var/lib/mpd/tagcache.bak || true - Ensure MPD owns its directories:
Code
sudo chown -R mpd:audio /var/lib/mpd /var/log/mpd /etc/mpd.conf sudo chmod 750 /var/lib/mpd
2. Networking: remote clients, TLS, and binding
- Bind address: in /etc/mpd.conf set the audio_bind_to_address and port in the “audio_output” and “bind_toaddress” (listen) fields. Example to allow LAN clients only:
Code
bind_toaddress “192.168.1.100” port “6600” - Allow any host (not recommended): use “0.0.0.0”.
- Firewall: open TCP 6600 for trusted subnets (ufw example):
Code
sudo ufw allow from 192.168.1.0/24 to any port 6600 proto tcp - TLS proxy: MPD lacks native TLS. Use stunnel or socat to terminate TLS and forward to localhost:6600.
- stunnel minimal: terminate TLS on 6601 and forward to 6600; run stunnel as a system service.
- Access control: restrict by bind address + firewall. For per-client auth, run MPD behind an SSH tunnel for untrusted networks.
3. Multi-room & networked audio
- Pipe outputs and network
