We would like to present to you two great projects, that our forum user Tobi81 has created with Max2Play. On one hand, a cheap 2.1 All-in-One audio system with Wi-Fi, USB input and jack plug and on the other hand, a flatpanel mono loudspeaker with a built-in Raspberry Pi Zero:

Nevertheless, I have now bought the following 3.5 watt amplifier, which I would like to install soon. The sound with this one, I will report at another time. …
