@xogium I made a similar thing using a pi0 and a wm8960 chip with 2 ohm speakers.
@fireborn Nice. I'd use a mcu over a linux capable board if I ever manage to build it, for several reasons.
One, it would boot much, much, much faster and be capable of realtime. Second being that, well... Relying on a system that is notorious to destroy your audio when it just feels like it... Yeah. Nop.
I totally understnad why you went that route, but for an actual viable product I'd definitely go with a microcontroller.
