AirPlay on the RaspberryPi

I bought a Wolfson Audio Card and a new RaspberryPi (as my original Pi is too old to work with the card…) for the sole purpose of using it as a sound source for my stereo. The idea would be to have AirPlay enabled to allow iTunes / my iPhone to stream to it and to have MPC/MPD installed so I can stream radio / play high-res audio files over a network share. This requires the wonderful Shairport.

This is the process I went through.

• Download Ragnar’s wheezy .img file (that includes the patches to get the Wolfson card to work)

• I zero’d the SD card

• sudo diskutil unmount /dev/disk1s1<br /> sudo dd bs=1m if=~/RasPi/2014-01-07-wheezy-raspbianW.img of=/dev/rdisk1<br /> sudo diskutil unmount /dev/disk1s1<br /> sudo diskutil unmount /dev/disk1s2

• Boot and access (I do this headless)

• sudo apt-get update

• Install netatalk – this allows the pi to be seen on the .local domain – sudo apt-get install netatalk. This installs netatalk and avahi for Bonjour services.

• Added a afp.service and a ssh.service file to /etc/avahi/services following this to get pretty icons and the like.

• Install shairport as detailed here.
  git clone https://github.com/abrasive/shairport.git<br /> cd shairport<br /> ./configure<br /> make<br /> sudo make install

  Move the scripts into the correct locations:

  sudo cp scripts/debian/init.d/shairport /etc/init.d/.<br /> sudo cp scripts/debian/default/shairport /etc/default/.<br /> sudo cp scripts/debian/logrotate.d/shairport /etc/logrotate.d/.<br />

• I changed the name the Pi broadcasts and made the service start on boot as per instructions found when googling.
• Run the lineout script from the use_case_scripts directory. This selects the Wolfson card as the sound output device.
• sudo apt-get install mpd mpc flac to get internet streaming and file playing.
• For hi-def audio: sudo apt-get install lxmusic xmms2 xmms2-plugin-all volumeicon-alsa mpg123 mplayer
• To be able to load from usb sticks etc with HFS support: sudo apt-get install hfsutils hfsprogs

After all that you should have a Pi that appears as a set of AirPlay speakers within iTunes and on your iPhone. You should also be able to play music using MPC.
