Raspberry Pi

Mopidy runs on all versions of Raspberry Pi. However, note that Raspberry Pi 2 B’s CPU is approximately six times as powerful as Raspberry Pi 1 and Raspberry Pi Zero, so Mopidy will be more joyful to use on a Raspberry Pi 2.

How to for Raspbian Jessie

  1. Download the latest Jessie or Jessie Lite disk image from http://www.raspberrypi.org/downloads/raspbian/.

    If you’re only using your Pi for Mopidy, go with Jessie Lite as you won’t need the full graphical desktop included in the Jessie image.

  2. Flash the Raspbian image you downloaded to your SD card.

    See the Raspberry Pi installation docs for instructions.

  3. If you connect a monitor and a keyboard, you’ll see that the Pi boots right into the raspi-config tool.

    If you boot with only a network cable connected, you’ll have to find the IP address of the Pi yourself, e.g. by looking in the client list on your router/DHCP server. When you have found the Pi’s IP address, you can SSH to the IP address and login with the user pi and password raspberry. Once logged in, run sudo raspi-config to start the config tool as the root user.

  4. Use the raspi-config tool to setup the basics of your Pi. You might want to do one or more of the following:

    • Expand the file system to fill the SD card.
    • Change the password of the pi user.
    • Change the time zone.

    Under “Advanced Options”:

    • Set a hostname.
    • Enable SSH if not already enabled.
    • If your will use HDMI for display and 3.5mm jack for audio, force the audio output to the 3.5mm jack. By default it will use HDMI for audio output if an HDMI cable is connected and the 3.5mm jack if not.

    Once done, select “Finish” and restart your Pi.

    If you want to change any settings later, you can simply rerun sudo raspi-config.

  5. Once you’ve rebooted and has logged in as the pi user, you can enter sudo -i to become root.

  6. Install Mopidy and its dependencies as described in Debian/Ubuntu: Install from apt.mopidy.com.

  7. Finally, you need to set a couple of config values, and then you’re ready to run Mopidy. Alternatively you may want to have Mopidy run as a system service, automatically starting at boot.

Testing sound output

You can test sound output independent of Mopidy by running:

aplay /usr/share/sounds/alsa/Front_Center.wav

If you hear a voice saying “Front Center”, then your sound is working.

If you want to change your audio output setting, simply rerun sudo raspi-config. Alternatively, you can change the audio output setting directly by running:

  • Auto (HDMI if connected, else 3.5mm jack): sudo amixer cset numid=3 0
  • Use 3.5mm jack: sudo amixer cset numid=3 1
  • Use HDMI: sudo amixer cset numid=3 2
