No clue how DSD normally is output (if it's a simple 1-bit stream, then you can abuse I2S for it for sure) but DSD-over-PCM seems to be made to work fine if you use an I2S-to-PCM converter of some kind.

Can't find a specification for DSD (
"Direct Stream Digital"), but it appears to be based on PDM which the ESP can do
via I2S. Don't know if I2S PDM is compatible with DSD though.
