Configuration

See Configuring Shairport Sync

Remember start avahi-daemon if you run shairport-sync mannually:

# systemctl start avahi-daemon
# shairport-sync

What's more

It takes a little more work to let shairport-sync run as system service with pulseaudio. Here is an example:

First emerge pulseaudio with system-wide support. The system-wide USE flag is masked, so we have to unmask it(See Pulseaudio):

# mkdir -p /etc/portage/profile`
# echo "-system-wide" >> /etc/portage/profile/use.mask`
# echo "media-sound/pulseaudio system-wide" >> /etc/portage/package.use`
# emerge --ask --oneshot pulseaudio`

To allow multiple users to use PulseAudio concurrently, add following line to /etc/pulse/system.pa :

load-module module-native-protocol-unix auth-anonymous=1 socket=/tmp/pulse-socket

Configure pulseaudio backend in /etc/shairport-sync.conf :

pa =
{
        server = "unix:/tmp/pulse-socket";
};

Finally, start and enable services:

# systemctl start pulseaudio
# systemctl start shairport-sync
# systemctl enable pulseaudio
# systemctl enable shairport-sync
