Applies to: Scarlett Range
You will notice that the only sample rate options found within Windows -> Sound -> Playback Devices is the sample rate currently selected for the Scarlett Interface (and the various bit-rates within that, 16bit, 24bit etc).
In order to change the sample rate of your Scarlett you need to open the driver control panel. This is located in:
Windows icon/Start menu -> All Apps -> Focusrite -> ASIO Control Panel
