Without the code, there is no way of knowing what you are doing wrong.

amix can only work with float samples (hat is one of the reasons I
discourage people of using it; use amerge and pan, they support many
formats); since your input has integer samples, resample is inserted to do
the conversion.

No, that is completely unrelated.
