Same program with the same language model can't detect words on Windows but works on Mac

I'm using Vosk with node.js on Max MSP.
I've got a patch that works fine on Mac using the vosk-model-en-us-0.22 language model.
Just installed the same thing (node.js/vosk/sox/exact same language model) on a Windows machine, changed nothing but the file paths. Everything seems to be running with no error in the log. But it just won't detect the words correctly. Even on the rare occasions when it does, it's almost always wrong. There should be no problem with the audio input, as the program shows the mic volume in real time. Tested in a relatively quiet office environment.

Any suggestions?
