WavePCI and Resampling

Hi,

I'm currently developing a WDM audio driver using WavePCI.

I need to know how to ask KMixer to change the resampling parameters
dynamicallly.

Right now, I force the sampling freq to a fixed value (when KS call
SetFormat, the function accept only one value)

Is it possible to change the values dynamically (ie while a window media
player is playing).?

Thank you.

Regards,
Farid
