I could now reproduce your issue with a libsoxr enabled ffmpeg. It appears that libsoxr produces slightly different results each time, as if rounding arbitrarily. It seems indetermenistic. You should take it up with libsoxr. The try native resampler, but with some of the other dither methods described in $ ffmpeg -h filter=aresample and in the "Resampler Options" section of ffmpeg's documentation.
