The jack server is playing the role of kernel audio mixer in linux but it just mixing all the jack clients at the server 's sample rate only
Correct. However, Wine mixes all secondary buffers of the application into primary before sending the result to jack. And while mixing secondary buffers into primary, Wine resamples (badly, using zero-order hold) if there is a mismatch in the sample rates of primary and secondary buffers.
