I got excited about the idea of having a Raspberry Pi. It is in essence one of the smallest complete computer that you can get for $35 bucks! Ok, after I got one I had to do something useful with it… So I make it a Airplay receiver to play music remotely from any of my apple devices!
There is a couple of ways to make it work. The easiest one is to install the RaspBMC, a popular media center.(http://www.raspberrypi.org/downloads) You can even turn it into a home theater (http://www.makeuseof.com/tag/raspberry-pi-home-theater-system/). However, I’m not going to explain any of those ways because just installing them gives you 99% of the functionality. As a developer, I want to have control of the computers, and I’m not afraid of the console. So, I installed Raspbian instead, which is a lightweight Ubuntu/Debian Linux optimized for Raspberry Pi.
1. Install Raspbian “wheezy”
Download the image from http://www.raspberrypi.org/downloads and follow the instructions. You have to format the SD card and “copy” the image. You can download this formatting tool: https://www.sdcard.org/downloads/formatter_4. After that, plug the SD card in Raspberry, also the Ethernet cable and power cord. For more instructions follow http://lifehacker.com/5976912/a-beginners-guide-to-diying-with-the-raspberry-pi.
2. Setup Pi
You need to connect it to an HDMI display to set it up using a USB mouse and keyboard or you can use SSH if you had set that up.
3. Access the Terminal
From the terminal type the following commands in you Raspberry Pi:
Become root and update the system
sudo apt-get update && sudo apt-get upgrade
3. Setup Audio
Audio ports could either be bind to the HDMI connection or to the audio output jack (you need sudo to execute any sound command).
sudo amixer cset numid=3 1
Connect the speakers to you Raspberry Pi. You can test that they work with these:
sudo speaker-test -t pink -l 1
You can also adjust the volume
4. Install Airplay software
I tested with 2 different programs, both of them did the trick for me.
The latter is more popular so I will give the instructions for that one:
apt-get install -y libssl-dev libavahi-client-dev libasound2-dev git
5. Run Airplay (shairport) on boot.
It’s nice to run airport receiver automatically when you connect your Pi.
Create a file to start shairport
Type the following into
Close the editing mode and exit the file. Then register the script to be run on boot.
chmod a+x /etc/init.d/airplay
Reboot your Pi and you are good to go! (If you have any questions you can write a comment below)
