Shairport Sync is working on Raspberry Pi with Raspian and OpenWrt, and it runs on a Linksys NSLU2 using OpenWrt. It also works on a standard Ubuntu laptop. It works well with built-in audio and with a variety of USB-connected Amplifiers and DACs, including a cheapo USB "3D Sound" dongle, a first generation iMic and a Topping TP30 amplifier with a USB DAC input. It also works with the IQAudIO PiDAC on their customised version of Linux on the Raspberry Pi.

Shairport Sync compiles and runs pretty well on the built-in sound card of a Raspberry Pi model B under Raspian. Due to the limitations of the sound card, you wouldn't mistake the output for HiFi, but it's really not too shabby.
USB-connected sound cards work well, so long as the wired Ethernet port is not in use -- WiFi is fine if the network is not too busy. However, driving any USB-based audio output device is glitchy if you are using Ethernet at the same time or if you're on a busy WiFi network. It works, but it's very glitchy. This seems to be due to a known problem -- see http://www.raspberrypi.org/forums/viewtopic.php?t=23544 -- and it will hopefully be fixed in a forthcoming update to Raspian.

The settings used are the most basic defaults, so you will want to edit the file `/etc/init.d/shairport` to give the service a name, use a different card, use the hardware mixer and volume control, etc.
