Solution
A new sound API was created in LabVIEW 8.0 for Windows and LabVIEW 2009 for Mac that supports 32- and 64-bit operating systems. This API calls functions from the
lvsound2.dll library and can be found in
Programming>>Graphics & Sound>>Sound in LabVIEW Functions Palette.
This library can be found in
<Program Files>\National Instruments\LabVIEW 20XX\vi.lib where XX represents the version of LabVIEW that you have installed. The DLL can be found in
<Program Files>\National Instruments\LabVIEW 20XX\resource\lvsound2.dll, be sure that both the library and DLL are in the correct folder or LabVIEW will be unable to call for the functions inside the palette.
You will need to modify your code and replace functions from the old sound API with functions from the new API. This will change your program to make calls from
lvsound2.dll instead of
lvsound.dll.
