If pulseaudio is involved, check these settings in /etc/daemon.conf

The default settings, I believe were 44100 and 48000 respectively and this
caused certain applications (skype, in particular) to have their signals
downsampled from 48k -> 44k. Was an interesting affect during skype
conversations but ultimately got annoying so I changed both settings above to
the same value (48000) and all is well.
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.
