Yesterday\u00a0afternoon, I had great fun setting up the JustBoom<\/a> AmpHAT. JustBoom<\/a> is a\u00a0new player in the Raspberry Pi audio market, but comes from well-known company Pi Supply<\/a>.\u00a0I was sent the full family of JustBoom boards for review by Aaron, but I’m free to say what I want about them.<\/em><\/p>\n Here are the specs:<\/p>\n This is the top-of-the-line combination DAC\/amplifier board, costing \u00a360, so I thought I’d see if it was worth it.<\/p>\n To use the board, I bought a couple of speakers<\/a> and a power supply<\/a>. In comparison to what I\u00a0could<\/em> have bought, the speakers were fairly cheap (\u00a380). I also grabbed some speaker wire<\/a>\u00a0so I could connect the speakers up.<\/p>\n I pretty much didn’t know what I was doing connecting the speakers to the AmpHAT. I knew enough, however, to make sure that the positive and negative terminals matched and the instructions provided with the speakers were clear enough.<\/p>\n I installed\u00a0OSMC<\/a>\u00a0onto an SD card and plugged it into a Raspberry Pi 3. I assumed that there was some automated set-up that would happen on first boot and, sure enough, the file system expanded and some software installed itself. I plugged in a USB pen-drive that contained some music in FLAC format<\/a>\u00a0(a format I knew to be of the highest quality) and selected a track to play.<\/p>\n Nothing happened.<\/p>\n I looked on the JustBoom website<\/a> for some help, but unfortunately the guides are yet to be written.\u00a0I hope they get them done soon as at the moment it really is difficult to know what to do<\/em>. I\u00a0contacted Alex Eames<\/a> (who I knew had got\u00a0one of the boards working) to find out what he did, but it was a Raspbian-only solution to do with editing the Pi’s config.txt file: not an option with OSMC. So, I did a little exploring in the OSMC settings and discovered that you needed to get OSMC to load up the JustBoom DAC\u00a0overlay file. I enabled this. Still nothing happened. I eventually found the setting to control where the audio was output to and selected the ALSA option. Suddenly, music blared out of the speakers, scaring the hell out of me! It worked! It worked! My first choice for music? Transformers: The Movie. For two reasons: first of all, I’ve always loved the music; secondly, I knew that it was a synthesised soundtrack with a lot of treble and a lot of bass, so I knew it would be a good workout for the system. Here is a video of the results. Please note, the sound is\u00a0so much better<\/em> than this – this is just on my mobile.<\/p>\n\n
