Do I understand correctly that the card internally resamples the sound 
to a different rate using the zero-order-hold method? If so, I'd rather 
not see this feature at all unless the "i_want_horrible_sound" parameter 
is passed, because software can do it better, and some program will 
surely default to using this hardware misfeature.

OTOH, Wine is doing this for ages and nobody except me complains
