I've been asked to record and deliver some tracks for someone at 48k 24 bit, but my Octa Capture has only one option showing 44.1k.  Sonar shows me other options but when I select one of them I get a message that "The default audio format is not compatible with one or more sound cards. It has been reset to 44100 Hz (32 bit), as suggested by the driver."  I went into Windows and deselected Octa Capture as the default, but still no options in the OC settings.  I'm not sure where to look to make this change.  Thanks for any help.
 
Windows 8
Sonar x2
Octa Capture
 
All drivers have been updated.

Before opening Sonar:
 
Press the OC Display button for over 1 second
Scroll down to Sample Rate with Cursor/Value knob
Push Cursor/Value knob
Rotate Cursor/Value knob to desired sample rate
Press Display again quickly to back out
Open Sonar and set Sample rate in preferences

You can do this in the OC's control panel.
 
Go to "Driver" and select "Driver Settings".
At the top of the dialog box there is a sample rate settings dropdown. You can choose which sample rate you like there.

These are the things I'd been trying, but the OC was only showing me one option of 44.1k.  After reinstalling the driver for a third time it straightened itself out.  Thanks for the replies though.

Weird. Did you uninstall previous versions before re-installing?
