I believe the Sound control panel will show 88.2 kHz as an option in Windows 7.

Ok, that means my application will still need to let the user set the 

But another question: When I let my device expose 8 channels, and I click "Configure 
Speakers..." to bring up the
config dialog, the "Audio channels" list is empty, whereas a USB device I have 
supporting 8 ch does have it populated
with "Stereo/Quadraphonic/5.1 Surround/7.1 Surround".

Also, when I let my device expose 2 channels, the "Audio channels" list contains 
"Stereo" only (of course).

How do I get "Configure Speakers" to show the Stereo/Quad/5.1/7.1 configs ?

KSPROPERTY_AUDIO_CHANNEL_CONFIG is implemented and returns 0xFF when queried 
(in 8 ch mode).
