Issue Details

I would like to list all my sound devices and their Device IDs that are needed for the Sound Output Input Sound How can I achieve that?


To acquire device names and IDs, you could make use of the Sound Device, which is located under \LabVIEW XXXX\vi.lib\sound2\lvsound2.llb. The example below shows one way of achieving it. 
Note: This image is a LabVIEW snippet, which includes LabVIEW code that you can reuse in your project. To use a snippet, right-click the image, save it to your computer, and drag the file onto your LabVIEW block diagram.

Additional Information

The Device IDs would be in the range of 0 to n-1, n being the number of devices recognized in the Audio input and outputs section.

The 'Acquire Sound' Express VI that comes installed with LabVIEW can also be used to examine which are the  devices that are recognized.
