All mixing mechanisms (dmix, PulseAudio, hardware wavetable) require that their inputs are resampled to a common frequency. (It is no longer true that ALSA's resampling has very low quality.) > if it's possible to stop upsampling if it is happening Disable software mixing, i.e., use a "hw" or "plughw" device instead of "dmix".
