I recently had issues getting the PC to change to 48khz to sync with a Yamaha TF3 Sound board. And I found the way to do this by reading the PDF help file.
Go to Windows 10 Control Panel, Hardware and Sound, and then look for the Yamaha Steinberg USB Driver option in the list. Mine was last on the list. Then select the Yamaha TF tab and there you can select 48khz!
