Both of mine are set to 48k as well... Pulse complains at startup that 
alternate is the same as default  :) It doesn't really matter in my setup 
as pulse never has direct control of any audio interface, jack sets the 
sample rate, I have not noticed skype oddness.

For the OP, do you run the CPU in performance mode? Or is it ondemand? I 
would not think the CPU frequency would have anything to do with the 
sample frequency unless something was broken.... but running in 
performance mode is more stable anyway.
