Playing audio files in a Pi Pico without a DAC
Agreed.
While ΔΣ modulation, also known as pulse-density modulation, is not supported in "hardware" on Pi Pico, it is possible to do it in "software" with programmable IO, like in tierneytim's Pico-USB-audio project you're linking to.
Also, PDM input could be done in similar fashion: https://github.com/mkvenkit/mico
