Introduction
This is a very quick initial note about installing Shairport Sync on FreeBSD. Some manual installation is required.
Please see important notes at the end about using the sndio back end -- some workarounds are needed for the present.
The build instructions here install back ends for sndio (native to OpenBSD) and ALSA. ALSA is, or course, the Advanced Linux Sound Architecture, so it is not "native" to FreeBSD. It has, however, been ported, so it should work pretty well.
General
This build was done on a default build of FreeBSD 11.0-RELEASE-p9.
First, update everything:
# freebsd-update fetch
# freebsd-update install
Next, install the pkg package manager and update its lists:
# pkg
# pkg update
Subsystems
Now, install the ALSA and Avahi subsystems. Note: avahi-app is chosen because it doesn’t require X11 and nss_mdns allows FreeBSD
to resolve mDNS-originated addresses. Thanks to reidransom for this:
# pkg install alsa-utils avahi-app nss_mdns
To enable these services to load automatically at startup, add these lines to /etc/rc.conf:
dbus_enable="YES"
avahi_daemon_enable="YES"
Next, change the hosts: line in /etc/nsswitch.conf to
hosts: files dns mdns
Reboot for these changes to take effect.
Building
Next, install the packages that are needed for Shairport Sync to be downloaded and build successfully:
# pkg install git autotools pkgconf popt libconfig openssl sndio
Now, download Shairport Sync from GitHub and check out the development branch.
$ git clone https://github.com/mikebrady/shairport-sync.git
$ cd shairport-sync
$ git checkout development
Next, configure the build and compile it:
$ autoreconf -i -f
$ CPPFLAGS="-I/usr/local/include" ./configure --with-alsa --with-avahi --with-sndio --with-ssl=openssl --with-metadata
$ make
Manual Installation
After this, you're on your own – the $ sudo make install step does not work for FreeBSD. Maybe some day...
To continue, you should create a configuration file at /usr/local/etc/shairport-sync.conf. Please see the sample configuration file for more details.
Using the sndio backend
The sndio back end does synchronisation, thanks to the work of t6, using information from the sndio subsystem. The format of the information is not the same as that coming from the ALSA subsystem, so Shairport Sync cannot yet use it properly. As a workaround, please use the following settings:
In the general stanza of the configuration file at /usr/local/etc/shairport-sync.conf, make the following settings:
drift_tolerance_in_seconds = 0.005; // allow some more tolerance before attempting to correct
resync_threshold_in_seconds = 0.0; // ignore a large error in the initial estimation of synchronisation time...
Note that there are workarounds -- it is hoped that they won't be necessary for too long.
Setting Overall Volume
Note, the mixer command is useful for setting the output device's overall volume settings. With the default settings for the sndio back end, the pcm mixer controls its maximum output:
$ mixer vol 100 # sets overall volume
$ mixer pcm 100 # sets maximum volume level for the default sndio device used by Shairport Sync
