This looks very cool.

Since a Raspberry Pi Pico doesn’t have built-in audio output ports, I think the main thing blocking ordinary people from using it is figuring out the hardware? A link to a tutorial for how to add audio output would be useful.

Thank you! I will soon be producing a comprehensive introductory video on YouTube, which should make things more accessible.

There will also be an official plug-and-play custom board that includes all of the relevant IO, connectors and codecs.

    In the meantime, what would you recommend (if there's anything off-the-shelf that would work in a plug-and-play manner?)

    I had a project in mind that was waiting for something like this! :)

      For USB input and SPDIF output, all that you need is a TOSLINK TX module(s) or a couple of capacitors and a resistor if you want coaxial SPDIF. For I2S output, the PCM5102A modules that you find on Amazon work very well, with very reasonable performance (SNR >100dB, THD+N ~95dB).

      For 2.1 configurations in a pinch, the firmware includes a software DAC that's more than adequate to drive a subwoofer, so only one external DAC is needed.

    Uh, some people like videos but I'd really rather have a web page with all the steps laid out and still photos. (And maybe links to the video, too?)

    A custom board sounds great, too.
