Yes, there seems to be a discreet list used to populate the default format choices. I've only ever seen multiples of 48K for rates above 48K.

Maybe someone else can confirm.

I've now implemented my device to expose each samplerate/channel combo as a separate KSDATARANGE item, and this is dynamic, i.e. I can tear down the device, update its KSDATARANGE items, then init the device again. And it "seems" as though the control panel of Vista can handle it.

Not quite. I forgot to mention that in one case I expose 44100,48000,88200,96000 as samplerates but 88200 Hz gets "dropped" in sound control panel.

Why? Is the audio subsystem in Vista/Win7 hardcoded to accept only a few selected samplerates ?

TIA
