it is because dsoutput.c explicitly disable the resampling of the "plug" or
"rate" plugin of the "default" device 

    snd_pcm_hw_params_set_rate_resample(pcm, hw_params, 0);

However this function has not effect on "pulse" plugin, i.e. pulse device still
support any rate within 1 Hz and PA_RATE_MAX Hz 

if your sound card does not support the requested rate (e.g. 22050Hz) , wine
have to do the resampling by itself
