I don't think my defaults.pcm.rate_converter is being obeyed. I
switched from "speexrate_best" to "samplerate_best" and also tried
removing the definition entirely, but lsof still says whichever
program is playing audio is opening the speex file and not the
libsamplerate file.
I also tried removing speex from the system and speex disappeared from
lsof, but the static remained.

I can definitely confirm static with aplay .wav files that doesn't
exist in mpd. If I don't have mpd bypass dmix I get static there too.
Where should I go from here?
