Issue Details

I'm trying to communicate with a USB microphone from LabVIEW using the sound VIs, however none of the Device IDs I've tried work, how can I communicate with the microphone from LabVIEW? 

Solution

LabVIEW's sound VIs  should be able to communicate with any microphone that is properly recognized in the Windows Device Manager in the 'Audio inputs and outputs' section.

If the microphone is recognized correctly in the Device Manager, and LabVIEW is not able to communicate with the device, restart the computer with the microphone already plugged in, as it may not have been properly registered for LabVIEW to use it.

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.
