Just for fun, I tried turning a CP2102 USB UART adapter into a PDM DAC, using the raw output of the serial bitstream. It sounds "not good", but honestly not that bad either. Here's a sample from it: https://retr0.id/media/5c4c16ac-bc6d-4bf0-9159-73bbe4fcfb02/out.mp3 https://retr0.id/media/5c4c16ac-bc6d-4bf0-9159-73bbe4fcfb02/... The only external components were a simple passive RC filter.

I did this a while back: https://hackaday.com/2005/10/25/audio-output-from-a-serial-port/ https://hackaday.com/2005/10/25/audio-output-from-a-serial-p... (Looks like somebody mirrored it to github at https://github.com/koniu/ttyplay https://github.com/koniu/ttyplay)

It sounds "fluttering" as if there's periodic pauses in the bitstream being sent.
