Hey,
As I hear / see windows audio settings is overriding your interface settings.
I believe you can solve this by setting the sample frequency in your windows audio settings
Quote from the net :
Right-click the Speaker icon in your system tray and click Playback devices.
Select your speaker, then click Properties.
Click the Advanced tab.
Click the drop-down and it will show you the sample rate and bit depths options
Choose option and click apply then OK..

This sets windows to your desired frequency and will no longer try to change your interface settings... { if everything goes right}
Good luck and let us know if this worked
