YOU’LL NEED THIS RASPBERRY PI OR PI ZERO
Plus a 4GB or larger microSD card.
CABLE Capable of connecting your Pi to an
amplifier or your home stereo. WE’RE GOING TO TRANSFORM YOUR RASPBERRY PI into a music player with Volumio, a distro that has just one job: playing and streaming music. It’s relatively easy to set up, is designed for headless use, and provides a user-friendly interface through your web browser for managing your music. This UI is replicated on the official Volumio apps for iOS and Android, so you can run everything from your cell phone, too. You can also access Volumio through your mobile browser, or try an MPDcapable app, such as MPDroid for Android, instead. Note, however, that MPD apps can be tricky to set up (connecting using IP address rather than hostname is more reliable).
Volumio also doubles up as a UPNP/DLNA and AirPlay receiver, and can be used to stream music over the Internet, with built-in support for web radio, and plugins for streaming from Spotify and YouTube, too. Volumio supports the most popular audio file formats out of the box—including FLAC for those of us who have an aversion to lossy compression—and has native support for a wide range of I2S DACs for those who want to take their listening pleasure to the next level. – setup is complete, your browser should redirect you to the main Volumio playback screen. You’ll see that it’s split into three tabs: Browse, Playback, and Queue [ Image A]. They’re all self-explanatory, so start by clicking “Browse,” where you’ll see you can navigate your collection. Look out for the spinning wheel at first. This indicates that your folders are still being scanned for content. 3 CONFIGURATION OPTIONS While you wait for the initial scan, click the “Settings” button in the top-right corner to find a range of configurable options. Start with “My Music,” where you can add new drives to your library. You can also tweak other preferences here, such as whether to download album art from the web, for music folders without art in them. Consider switching this off if your album art is embedded directly into each music track (you also need to flick the “Show Embedded Album Art” switch on, then click the “Reset Album Art Cache” button). If you find that certain artwork comes up missing or corrupt, chances are there are hidden folder.jpg files in the album folder downloaded from the web. Browse to the album folder in File Manager, and select “View > Show Hidden Files” to reveal the hidden .jpg album art files. Delete these, then repeat for any other afflicted folders. Once complete, go to “Settings > My Music,” and click “Reset Album Art Cache > Rescan” to update the album art.
Select “Playback Options” to change your output device and adjust related settings. Explore “Playback Options” if you experience frequent buffering when listening to music over the network. Increase the “Audio Buffer Size” to 12MB, and consider upping the “Buffer Before Play” figure. You can tweak Volumio’s volume options from here, too, such as setting a default volume on startup, or limiting the maximum volume level.
The “Appearance” settings affect the web ( and Volumio app) interface, enabling you to change language, select a background image (or upload your own), or choose a plain background color [ Image B]. Access “Network Settings” to configure the wired and wireless interfaces— typically to establish a static IP address. You can disable
