As an intermediary fix for those that just want to listen to their music... (which does not fix the actual bug ;) )
Change the Service Type to 'simple' instead of forking and remove the '--daemon' argument from ExecStart, aka resulting file: /lib/systemd/system/shairport-sync.service ``` [Unit] Description=ShairportSync AirTunes receiver Documentation=man:shairport-sync(7) Documentation=file:///usr/share/doc/shairport-sync/README.md.gz Documentation=https://github.com/mikebrady/shairport-sync After=sound.target Requires=avahi-daemon.service After=avahi-daemon.service [Service] Type=simple Restart=on-failure EnvironmentFile=-/etc/default/shairport-sync ExecStart=/usr/bin/shairport-sync $DAEMON_ARGS User=shairport-sync Group=shairport-sync PIDFile=/run/shairport-sync/shairport-sync.pid [Install] WantedBy=multi-user.target ``` Then: systemctl daemon-reload and: /etc/init.d/shairport-sync start Voila, music works again ;) This works as apparently only daemon mode is affected.
