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 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.
I mean, I know what you meant, but that's pretty misleading phrasing for many people.
It's not much of a stretch to think that most people interpret a "USB sound card" as a thing with analog audio on one side and USB on the other side. But other than the subwoofer output, we don't have any analog IO on a Pico running this firmware.
It is not 100% plug and play as you can choose your own software.
