RaspyPlay4 – the hardware hacker's answer to high end audio on a low end budget – has two more software options. Along with RuneAudio and Volumio now it also works Moodle audio and Max2Play.
As for hardware, it's important to know that it's compatible with Raspberry Pi 3. It always has been, but it wasn't listed on our specs page for some reason.
For the uninitiated, RaspyPlay is our side project that we launched in collaboration with Eurogenyx. As the British magazine Micro Mart put it: it is "perfect for Raspberry Pi enthusiasts who demand better audio output".
