Hi bk,
As this board may not be supported for that toolbox, one alternative you may want to consider is using some of the native LabVIEW functions included in the NI Sound and Vibration Measurement Suite. For additonal information on this toolkit you may goto the following link:

Another option you may want to consider if you are simply acquiring with the USB-9233 and are attempting to do some post processing with your own signal processing algorithm, is just integrating this custom graphical or custom text-based algorithm into LabVIEW.
For your reference, here is a webcast that describes how one can get started with acquisition and post processing in LabVIEW:

To download an evaluation version to try out you may goto:
LabVIEW 8.5 Evaluation Software Download

(once you have LabVIEW you will also be able to take advantage of the many built-in example programs available for the 9233 as shown in the attached screenshot)
I hope this helps. Have a great day!
Best regards,
Steven
