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 achieve this.

The "isInput?" bool option provides the user with the ability switch between listings of either input (such as microphones) IDs or output (such as speakers or headphone) IDs.

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.
