There are 2 places.  In the backend setup, where you define a capture 
card, you can set a sample rate *limit* for that card.  (Actually, I 
don't really know what that does... presumably it won't record higher 
than that rate for that card).  The setting you probably need to 
adjust, though, is in your recording profile, under Setup->TV 
Settings->Recording Profiles.  There's a setting for 'Audio sample 
rate'.
