    Sonos Airplay

Stream audio to any Sonos component via AirPlay using a
Raspberry Pi (Model B, Raspbian Jessie) and the following software:

Shairport Sync: configures the Raspberry Pi as an AirPlay audio player.
DarkIce: encodes audio received from AirPlay (system audio) and sends it to
Icecast2.
Icecast2: serves streaming audio from DarkIce at a network URL.
